Question #fe942

Answer 1

Valence electrons are the electrons found in the highest energy level of an atom - they determine how atoms of different elements will bond and react.

Explanation:

The video below shows how to determine the number of valence electrons for representative elements (s and p block).

This video reviews the technique for writing an electron configuration - which is used to determine the number of valence electrons an atom has (valence electrons are the electrons in the highest energy level of an atom).

This next video discusses how the number of valence electrons determines how atoms of different elements will react for form ionic compounds.

This final video shows how you can use information about the valence electrons of non-metallic atoms to determine how bonding works in molecular compounds.

Hope this helps!
