Question

examples of silicon and oxygen​

Answer 1

Answer:

The electronic configuration of the element is – K=2, L=8,m=4. According to the electronic configuration the valency is +4 or -4 because silicon can either gain 4 electrons or lose 4 electrons because it is a noble gas. Hence, valency of silicon is

Answer 2

Valency of silicon

• Atomic number of silicon is 14.

• The electronic configuration of the element is – K=2, L=8,m=4.
• According to the electronic configuration the valency is +4 or -4 because silicon can either gain 4 electrons or lose 4 electrons because it is a noble gas.
• Hence, valency of silicon is 4.

Valency of oxygen

• Atomic number of Oxygen is 8.

• Electronic configuration – K=2, L=6.
• According to the electronic configuration the valency is 6, but it is easy for oxygen to gain 2 electrons instead of loosing 6 electrons.
• Hence, the valency of oxygen is 2.
