Question

How many number of neutrons are there in Na2311​

Answer 1

Answer:

1000 thnx ! have a good day.

Answer 2

Answer:

The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23.

Therefore,

An atomic number of 11 means this atom will have 11 protons.

A mass number of 23 means 23 - 11 this atom will have 12 neutrons.

OR

Given - Mass number of atom = 23

Atomic number of atom = 11

As, no. of electrons in an atom is equal to an atomic number of the element.

So, number of electrons = 11

Secondly , number of protons are equal to number of electrons.

so, number of protons = 11

And number of neutrons = mass number - atomic number = 23−11 = 12

so, number of neutrons = 12

So , the atom contains 11 protons, 11 electrons, 12 neutrons.
