Question

5th group elements the metalic value increase or decrease​

Answer 1

Explanation:

The nitrogen family includes the following compounds: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is equal to the principal quantum number. The nitrogen family is located in the p-block in Group 15, as shown below.

Periodic Trends

All Group 15 elements tend to follow the general periodic trends:

Electronegativity (the atom's ability of attracting electrons) decreases down the group.

Ionization energy (the amount of energy required to remove an electron from the atom in its gas phase) decreases down the group.

Atomic radii increase in size down the group.

Electron affinity (the ability of the atom to accept an electron) decreases down the group.

Melting point (amount of energy required to break bonds to change a solid phase substance to a liquid phase substance) increases down the group.

Boiling point (amount of energy required to break bonds to change a liquid phase substance to a gas) increases down the group.

Metallic character increases down the group.
