Question

a new species of nitrogen which is formed in order to get a noble gas configuration is​

Answer 1

Explanation:

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium's noble gas configuration becomes [Ne]3s1.

Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Answer 2

Question - The new species of Nitrogen

which is formed in order to get

a noble gas configuration is

a) N-

b) N3-

c) N3

d) N3+

Answer - b) N3- is the correct answer.

• The nearest noble gas to Nitrogen is Neon. The electronic configuration of Neon is - 1s²2s²2p⁶, which means it has total number of ten electrons.
• The electronic configuration of nitrogen is - 1s²2s²2p³, which means it has total number of seven electrons.
• To attain noble gas configuration, nitrogen lacks three electrons. Hence, increase in three electrons will achieve noble gas configuration for nitrogen and hence stability.
• Thus, N3- of nitrogen will be similar to noble gas configuration.
