Answer 1

Answer:

The number of atoms present in one molecule of an element is called its atomicity. Example. Noble gases (helium, neon, argon, krypton, etc.)

Answer 2

⠀⠀⠀⠀⠀⠀⠀ᴀᴛᴏᴍɪᴄɪᴛʏ

ᴀᴛᴏᴍɪᴄɪᴛʏ is the number of atoms present in a molecule of an element.

Example :-

• Number of atoms present in the molecules of N₂ is 2 ,thus the atomicity of N₂ is 2. It is diatomic.

• Number of atoms present in the molecules of N₃ is 3 ,thus the atomicity of N₃ is 3. It is triatomic.

MORE TO KNOW

• Atomic mass of an element is a number which express as to how many times an atom of the element is havier than 1/12th of the mass of carbon atom.

• Atomic number is the number of protons present in the nucleus or the number of electrons present outside the nucleus of an atom of an element.
