(1) How do electrons move in an atom and what energy levels do they occupy? What is xoilac tv trực tiếp bóng đá hôm nay sequence of these energy levels? What principles and rules govern xoilac tv trực tiếp bóng đá hôm nay distribution of electrons in an atom?

- According to xoilac tv trực tiếp bóng đá hôm nay Rutherford-Bohr atomic model, electrons move on definite round or oval orbits around xoilac tv trực tiếp bóng đá hôm nay nucleus.

- According to xoilac tv trực tiếp bóng đá hôm nay modern model, in an atom, electrons move very fast around xoilac tv trực tiếp bóng đá hôm nay nucleus without following a definite orbit, forming an electron cloud.

- Electrons are arranged into shells and subshells by increasing energy levels.

- Sequence of energy levels arrangement:

+ Electrons in xoilac tv trực tiếp bóng đá hôm nay same subshell have equal energy.

+ Electrons in xoilac tv trực tiếp bóng đá hôm nay same shell have nearly equal energy.

(2) Compare and contrast xoilac tv trực tiếp bóng đá hôm nay Rutherford-Bohr model with xoilac tv trực tiếp bóng đá hôm nay modern model describing electron movement in an atom.

Similarities: Electrons move around xoilac tv trực tiếp bóng đá hôm nay nucleus.

Differences:

- According to Rutherford-Bohr: xoilac tv trực tiếp bóng đá hôm nay nucleus is in xoilac tv trực tiếp bóng đá hôm nay center, electrons move around xoilac tv trực tiếp bóng đá hôm nay nucleus on defined paths that are circular or oval.

- According to xoilac tv trực tiếp bóng đá hôm nay modern model: Electrons move chaotically without a defined orbit around xoilac tv trực tiếp bóng đá hôm nay nucleus ⇒ Only xoilac tv trực tiếp bóng đá hôm nay space in which electrons move can be determined, called xoilac tv trực tiếp bóng đá hôm nay atomic Orbital.

(3) Indicate which shell has xoilac tv trực tiếp bóng đá hôm nay strongest and which has xoilac tv trực tiếp bóng đá hôm nay weakest attraction to xoilac tv trực tiếp bóng đá hôm nay nucleus?

xoilac tv trực tiếp bóng đá hôm nay nucleus's attraction to xoilac tv trực tiếp bóng đá hôm nay K shell is xoilac tv trực tiếp bóng đá hôm nay strongest, and to xoilac tv trực tiếp bóng đá hôm nay Q shell is xoilac tv trực tiếp bóng đá hôm nay weakest.

...

What are forms, methods, and tools for assessing Chemistry subject in Vietnam?

Based on Subsection 3, Section 7 of xoilac tv trực tiếp bóng đá hôm nay General Education Program for Chemistry issued together withCircular 32/2018/TT-BGDDT, xoilac tv trực tiếp bóng đá hôm nay forms, methods, and tools for assessing xoilac tv trực tiếp bóng đá hôm nay Chemistry subject are as follows:

(1)Đánh giá thường xuyên:

Combining formative assessment (continuous assessment), summative assessment (periodic assessment), and large-scale assessments at xoilac tv trực tiếp bóng đá hôm nay national, local, and international levels to ensure comprehensive, frequent assessment integrated into xoilac tv trực tiếp bóng đá hôm nay teaching and learning activities of teachers and students.

(2) Assessment methods and tools:

- Combining teacher assessment with self-assessment and peer assessment by students.

Coordinating situational assessment; assessment through testing; assessment through projects and portfolios; assessment through feedback and reflection; assessment through observation.

- Combining assessment of learning products (essay tests, objective tests, oral responses, presentations, laboratory experiments, research projects, ...) with assessment through observation (attitude and behavior in discussions, group work, experiments, field trips, ...).

What are other orientations on teaching methods for Chemistry subject as per xoilac tv trực tiếp bóng đá hôm nay 2018 program in Vietnam?

xoilac tv trực tiếp bóng đá hôm nay General Education Program for Chemistry is issued together withCircular 32/2018/TT-BGDDTon other orientations on teaching methods for Chemistry subject as per xoilac tv trực tiếp bóng đá hôm nay 2018 program as follows:

* Orientations for methods of forming and developing essential qualities and general competencies

(1) Methods of forming and developing essential qualities

Through organizing learning activities, teachers help students form and develop a scientific worldview, cultivate honesty, love of labor, and a sense of responsibility;

Based on experimental, practical activities, especially field trips, laboratory practices, and production facilities to enhance students' awareness of protecting and rationally using natural resources, xoilac tv trực tiếp bóng đá hôm nay responsibility of workers, and safety principles in production, especially in chemical-related industries.

Teachers employ diverse learning forms to nurture students’ interest and confidence in learning, scientific exploration, respect for scientific labor results, and xoilac tv trực tiếp bóng đá hôm nay ability to apply scientific knowledge to life.

(2) Methods of forming and developing general competencies

- In teaching Chemistry, teachers organize activities for students to explore, discover, and practice science, especially searching and handling resources for self-learning (including digital resources), designing, and performing experiments, and learning projects to enhance students' self-reliance and self-learning.

- Chemistry has many advantages in forming and developing communication and cooperation skills as students often engage in group learning projects and laboratory experiments, allowing for xoilac tv trực tiếp bóng đá hôm nay exchange, presentation, sharing of ideas, and study content, creating opportunities for communication and cooperation.

- Solving problems and creativity are intrinsic to understanding and exploring xoilac tv trực tiếp bóng đá hôm nay scientific world.

Through Chemistry learning activities, teachers create opportunities for students to apply chemical knowledge to explore, discover, and identify problems in xoilac tv trực tiếp bóng đá hôm nay natural world and propose solutions, develop plans, and implement plans to solve problems creatively.

Employing project-based learning and teamwork methods help students objectively and truthfully identify and solve problems based on scientific analysis.

* Orientations for methods of forming and developing chemical competencies

(1) To develop chemical cognitive competence, teachers create opportunities for students to mobilize existing knowledge and experiences to participate in forming new knowledge.

Emphasizing activities that connect new knowledge with previously learned knowledge systems such as comparison, classification, systematization of knowledge, application of learned knowledge to explain objects, phenomena, or solve simple problems, ...

(2) To develop competence in exploring xoilac tv trực tiếp bóng đá hôm nay natural world through a chemical perspective, teachers employ some advantageous teaching methods such as visual methods (especially laboratory practices, ...), problem-based teaching methods, project-based teaching methods, ... enabling students to pose questions, identify issues to explore, independently seek evidence to analyze information, test predictions, hypotheses through conducting experiments, or searching and collecting information through books, xoilac tv trực tiếp bóng đá hôm nay Internet, ...,

Simultaneously, focusing on developing students’ chemical thinking through chemistry exercises that require critical, creative thinking (open-ended exercises, having multiple solutions, ...), exercises linked to practical content reflecting xoilac tv trực tiếp bóng đá hôm nay chemical essence, reducing computational exercises, ...

(3) To develop xoilac tv trực tiếp bóng đá hôm nay competence to apply knowledge and skills learned, teachers create opportunities for students to read, access, and present information on practical issues related to chemical knowledge and propose solutions.

Teachers need to focus on practicing xoilac tv trực tiếp bóng đá hôm nay skills of problem identification; research planning; problem-solving (collecting, presenting information, processing information to draw conclusions); evaluating problem-solving results; proposing solutions for remediation, improvement;

Simultaneously, incorporating STEM education into teaching to develop students' ability to integrate knowledge and skills of Mathematics, Technology, and Chemistry in researching and solving some real-life situations.
