Can u plz tell me what is the answer for this.
With a good explanation.
Thank you ​

Answer 1

Explanation:

According to the periodic table, Sodium is Na, while chlorine is Cl, so NaCl is an ionic compound where Na+ combines with Cl-, forming a NaCl. For sodium oxide, oxide ion is O2-, where we need 2 Na ions to balance the 2-, therefore, sodium oxide is Na2O

Hope it helps

Answer 2

Valency of chlorine Is 1, while that of Oxygen is 2

Step-by-step explanation:

The number of electron(s) required to make a completely filled outermost shell in chlorine is 1, and oxygen is 2.

All because the electronic configuration of both are as follows:

Chlorine = 2, 8, 7

Oxygen = 2, 6

Recall that a stable octet structure must be achieved, so, Sodium (Na) with 2, 8, 1 will combine as follows:

Na + Cl --> NaCl

4Na + O2 --> 2Na2O
