What are the tips for memorizing the Chemical Periodic Table for students in 2025?

Below is a detailed guide to help you easily and effectively memorize the Chemical Periodic Table for 2025:

1. Main Structure of the Periodic Table

Period: Horizontal rows (1 → 7), indicating the number of electron shells.

Group: Vertical columns (IA → VIIIA, IB → VIIIB), indicating the number of outermost electrons and chemical properties.

Element Block: Divided into s, p, d, f (based on the valence orbital type).

2. Main Element Groups to Remember

Alkali Metal Group (IA): Very reactive, strong reaction with water.

Alkaline Earth Metal Group (IIA): Less reactive than IA, but still reacts strongly with water.

Halogen Group (VIIA): Strong nonmetals, high oxidizing ability.

Noble Gas Group (VIIIA): Less reactive, stable.

*Tips for Memorizing the Periodic Table

1. Use Poems to Remember Element Groups

The poems help you easily remember the element names by group.

- Group IA - Alkali Metals:

Liệt Nang Không Rub Cô Fan Hốt

(Li, Na, K, Rb, Cs, Fr)

- Group IIA - Alkaline Earth Metals:

Bé Mai Can Sữa Bò Rót

(Be, Mg, Ca, Sr, Ba, Ra)

- Group IIIA - Aluminum Group:

Bố Alum Giang In Thép

(B, Al, Ga, In, Tl)

- Group VIIA - Halogens:

Fai Cô Bán Iốt At

(F, Cl, Br, I, At)

- Group VIIIA - Noble Gases:

Heo Nào Ar Kiếm Xe Rin

(He, Ne, Ar, Kr, Xe, Rn)

2. Learn by Atomic Number Order

Elements in the periodic table are arranged in ascending order of atomic numbers, so remembering some main elements will help you deduce the next element.

Try to memorize the atomic numbers of common elements like H, He, O, N, C, Na, Cl, Fe... to help you quickly ascertain the positions of other elements.

3. Learn Using Mind Maps and Colors

Print the periodic table, mark different groups with various colors to differentiate metals, nonmetals, noble gases.

Use mind maps to systematize the information:

Alkali Metals (IA) → red color

Alkaline Earth Metals (IIA) → orange color

Halogens (VIIA) → green color

Noble Gases (VIIIA) → purple color

What are the characteristics of the General Education Program for Chemistry in Vietnam?

Under Section 1 of the General Education Program for Chemistry issued together with Circular 32/2018/TT-BGDDT, the following provisions apply:

- Chemistry is a field of natural science studying the composition, structure, properties, and transformations of simple substances and compounds.

- Chemistry is closely integrated with both theory and experimentation, bridging other natural sciences such as physics, biology, medicine, and geology. Advances in chemistry are interconnected with new discoveries in the fields of biology, medicine, and physics. Chemistry plays an important role in life, production, contributing to socio-economic development.

- The achievements in chemistry are applied in fields such as materials, energy, medicine, biotechnology, agriculture, forestry, fishery, and many other areas.

- In the general education program, Chemistry is part of the natural science group at the upper secondary level, chosen by students based on career orientation, interests, and personal abilities. The subject of Chemistry equips students with core knowledge of chemistry and its applications in life, while also relating to many other educational fields.

- Along with Mathematics, Physics, Biology, Informatics, and Technology, Chemistry promotes STEM education, which is emphasized in many countries worldwide.

- The Chemistry curriculum is designed into topics to both consolidate content strands, develop knowledge and practical skills formed from lower levels, and help students gain deeper insights into the fundamental general knowledge of chemistry, serving as a basis for learning, working, and researching.

- Each academic year, students with career orientation requiring extensive chemistry knowledge choose three suitable study modules based on their interests and school conditions.

- These modules aim to fulfill deep differentiation requirements, helping students enhance knowledge and practical skills, applying learned knowledge and skills to solve real-world issues, and meeting career orientation requirements.

What are the regulations on tuition and expenses of educational and training services in Vietnam?

According to Article 99 of the Education Law 2019, regulations on tuition and expenses of educational and training services in Vietnam are as follows:

- Tuition is a contribution made by learners to partially or fully cover expenses of educational and training services. Tuition rate is determined based on road maps for assurance of expenses for educational and training services prescribed by the Government. For institutions of vocational education and higher education, this rate is calculated based on the Law on Vocational education and Law on Higher education.

- Expenses of educational and training services include the total amount of salary, direct costs, management costs and depreciation of fixed assets in direct or indirect service of educational operation in accordance with educational programmes.

Admission fees contributed by candidates when submitting an application or taking an entrance examination shall be determined based on road maps of accuracy and adequacy.

- Students at primary education level in public educational institutions are not required to pay tuition; in areas lacking public schools, primary school students in private educational institutions shall receive subsidies on tuition from the State, with the support rate specified by provincial People’s Councils.

- Pre-school children at 05 years of age in villages and communes with exceptional difficulties, ethnic minority areas, remote and isolated areas, coastal areas and islands shall be exempted from tuition.

- Pre-school children at 05 years of age beside those regulated in clause 4 of this Article and students at lower secondary education level shall be exempted from tuition based on road maps specified by the Government.

- Mechanisms for collecting and managing tuition and service fees of educational operation are prescribed as follows:

+ The Government shall set tuition collecting and managing mechanisms for public institutions of preschool education, general education, vocational education and higher education;

+ Provincial People's Councils shall set the tuition framework and detailed tuition rate and fees of services and assistance for educational operation in public educational institutions as authorised and at the proposal of provincial People's Committees;

+ Provincial People's Committees shall set collecting and using mechanisms for admission fees of each educational level under provincial management after receiving the approval from provincial People's Councils;

+ People-founded and private educational institutions are entitled to set the rate of their tuition and other service fees, ensuring expense recoupment and reasonable accumulation. Publicly announce expenses of educational and training services and fee rate as guaranteed in school’s establishment proposal; and on the basis of each educational course/level/year as prescribed by law.
