Question

Why does carbon show a valency of +4 and -4 ?

Answer 1

Answer:

as it has a property of tetra valency even it lose 4electrons or gain 4electrons there will be unstable of carbon atom.therefore instead of it share electrons.

Answer 2

$\huge\star{\underline{\red{\mathfrak{Answer}}}}$

Numbers of electron in carbon =6

Electronic configuration=2,4

As the valence shell has 4 electrons out of 8 .... 4 can be given or 4 can be taken... both of them are easy .... so show that can be valency of plus 4 and - 4 .
