Answer 1

Answer:

Electronic configuration

Explanation:

hope it will help you, ✌

Answer 2

Answer:

The number of valence electrons for molecules can be calculated by adding the valence electrons of all the atoms that form that respective molecule.

Here are some examples

C

O

: Each carbon dioxide molecule is formed from 1 C atom and 2 O atoms. We know that C has 4 valence electrons and that O has 6 valence electrons, which means that the number of valence electrons for 1
