The combining capacity of an atom is known as its valency. The number of bonds that an atom can form as part of a compound is expressed by the valency of the element.

Copper - Symbol - Cu.

It is a transition metal with variable valency.

Atomic number - 29

ELECTRONIC CONFIGURATION:

1S2 2S2 2P6 3S2 3P6 4S1 3d10

As d orbital electrons are tightly bound, so copper has variable valency.

IN CASE OF CUO: Cupric Oxide or Copper (II) oxide.

Copper valency is 2.

IN CASE OF Cu2O : cuprous Oxide or copper (I) Oxide

Copper valency is 1.
