Answer 1

Here are the answers to your questions:

7. The only non-metal on the left side of the periodic table is Hydrogen (H).

8. The atomic number of Boron (B) is 5 and that of Aluminum (Al) is 13. Adding these together gives 5 + 13 = 18, which corresponds to Argon (Ar).

9. Carbon has 6 electrons.

10. Silicon (Si) exists in a solid state of matter at room temperature.

11. The atomic mass of Sodium (Na) is approximately 22.99 atomic mass units (amu).

12. The symbol for Sodium is Na.

13. Oxygen (O) belongs to Group 16 of the periodic table.

14. Potassium (K) is in Period 4.

15. Calcium (Ca) has 20 electrons.
