Answer 2

• The valency of an atom is its ability to combine with other atoms. The valency of an element determines the number of bonds that an atom may make as a component of a compound.

• We're all familiar with the way electrons in an atom are organised into shells and orbitals.
• The electrons found in the atom's outermost orbit are known as valence electrons.
• The outermost shell may hold a maximum of 8 electrons, according to the Bohr-bury system.
• When the outermost shell is fully filled, there is only a little amount of chemical activity.
• Its combining capacity is likewise reduced to zero.
