What are requirements fpr grade 10 students regarding the Chapter of Chemical Bond of the grade 10 Chemistry in Vietnam?
At Subsection 2, Section 5 of the General Education Program in Chemistry issued together with Circular 32/2018/TT-BGDDT, grade 10 students must meet the following requirements in the Chapter of Chemical Bond of Chemistry:
| Octet Rule | - Demonstrate and apply the octet rule in the process of forming chemical bonds for Group A elements. |
| Ionic Bond | - Describe the concept and formation of an ionic bond (providing several typical examples following the octet rule). - State the structure of the NaCl crystal. Explain why ionic compounds are often in a solid state under normal conditions (in ionic crystal form). |
| Covalent Bond | - Describe the concept and provide examples of covalent bonding (single, double, triple bonds) when applying the octet rule. - Write the Lewis structures of some simple compounds. - Explain the concept of coordination bonding. - Differentiate between types of bonds (non-polar covalent bond, polar covalent bond, ionic bond) based on electronegativity. - Explain the formation of sigma and pi bonds through orbital overlap. - Present the concept of bond energy (covalent bonds). - Assemble molecular models, NaCl crystal (according to available models). |
| Hydrogen Bond and Van der Waals Interactions | - Explain the concept of the hydrogen bond. Apply it to explain the occurrence of the hydrogen bond (with highly electronegative elements: N, O, F). - State the role and effects of the hydrogen bond on the physical properties of H2O. - Explain the concept of Van der Waals interactions and their influence on the melting point and boiling point of substances. |
Regarding study topics:
| Chemical Bonds | - Write Lewis structures, use the VSEPR model to predict the geometry of some simple molecules. - Present the concept of AO hybridization (sp, sp2, sp3), apply it to explain bonds in some molecules (CO2; BF3; CH4;...). |
