Question

cation and anions present in CO2 ​

Answer 1

Answer:

y

Each element in this group contains four valence electrons. A unique feature of this group is that the elements can form different anions and cations. Carbon forms a 4- anion whereas silicon and germanium form 4+ cations.

Answer 2

Answer:

Well here Carbon will become the cation and Oxygen will be the anion

Explanation:

This is because as a anion Oxygen has a valency of -2 and as a cation Carbon will have the valency of +4, But that doesn't mean Oxygen and Carbon cannot be the opposite, as an anion, Carbon has a valency of -4 and as Oxygen cannot be a cation
