Question

An atom contain 22 neutrons in its nuclus an 18 electron around its . It contain proton in its nuclus , its atomin number is and Mass Number Is​

Answer 1

Answer:

Since the no. of protons = no. of electrons,

therefore the no. of protons = 18

Explanation:

The atomic no. is 18 and the element is Argon (noble gas).

HOPE THIS HELPS!!

Answer 2

Answer:

atomic number is depend on number of proton and if atom is neutral so number of electrons equal to the number of proton. so the atomic number is 18. mass number is equal to the nucleus mass and nucleus is consist of no of protons + number of Neutron.

22+18= 40

mass number is 40u

and element name is argon.
