Question

How are atomic masses and valencies related?

Answer 1

Answer:

The elemenents of the periodic table sorted by atomic mass

Atomic Mass Name chemical element number

1.0079 Hydrogen 1

4.0026 Helium 2

6.941 Lithium 3

9.0122 Beryllium 4

Explanation:

Answer 2

Answer: The electronic configuration of atomic number explains the valency of the element

Explanation:

For example :

Carbon - 6 (atm. No.) 》2,4

Therefore valency is 4

Oxygen - 8 》 2,6

Therefore valency is 2 (8-6=2)
