$\huge\bold\purple{Solution:-}$

☘ Answer:-

☞ Name of the element- Neon (Ne).

☞ No. of protons- 10.

☞No. of electrons- 10.

☞No. of neutrons- 12.

☘ Explanation:-

We know that,

Atomic no. is defined as the number of electrons or the number of protons in an atom.

Now, it's given that:- Atomic no. -10.

Thus,

* No. of electrons -10

and

* No. of protons- 10

Also we know that,

Mass number= No. of neutrons + no. of protons.

Now, let the number of neutrons in the given atom be x.

We have found that the no. of protons- 10.

Now, on substituting the values of mass number and the number of protons, we get,

22 = x + 10

=> 22 - 10 = x

=> 12 = x

Therefore, the number of neutrons present in the atom = 12.

➡ 10th element in the periodic table- NEON (Ne).
