An element X has mass number 23 and atomic number 11
state the number of protons in its nucleus

Open in App

Solution

Atomic number (Z) — The total number of an electron or proton in a neutral atom is considered an atomic number
The chemical properties of an element are determined by the number of protons in the nucleus
It is also known as the nuclear charge number
Atomic number = The total number of electrons or total number of proton in a neutral atom
Sodium is a chemical element with the symbol Na
Its atomic number is 11 and its mass number is 23, it belongs to group 1
It is a soft, silvery-white highly reactive alkali metal
So, the total number of protons in the nucleus of sodium is 11.
