PHYSICS1) Prepare a model to show the electrons distribution of elements from Hydrogen to Argon.2) Define valency by taking examples of Nitrogen and Boron?​

Answer»

Answer:

Hello my FRIEND

Explanation:

Define VALENCY by taking examples of nitrogen and boron.

It is the number of outermost electrons in the outermost ORBIT. Nitrogen has electronic configuration 2,5. ... So it will lose 3 electrons rather than gaining 5 electrons. Thus the valency of nitrogen and boron is 3.
