Question

Complete the following table:

Element Atomic

number

Electronic

configuration

Valence

electrons

Valency

Boron 5 (2,3) ________ ___________

Nitrogen 7 _________ _________ 3

Neon 10 ________ 0 _______​

Answer 1

Answer:

BORON= Z=5. A=10. electronic configuration = (2,3) Valence electrons =3. valency=3

NITROGEN. = Z=7. A=14. electronic configuration =(2,5) valence electrons=5. valency=3

NEON = Z=10. A=20. electronic configuration =2,8. valence electrons= 8. valency=0
