Question

Sodium has an atomic number of 11 and an atomic mass of 23. sodium has __________.

Answer 1

Sodium has 11 protons, therefore number of neutrons must be 23 – 11 = 12 neutrons.

Sodium has 12 neutrons.

What are neutrons?

The neutron is a subatomic particle with the symbol n that is slightly heavier than a proton and has a neutral charge (i.e., neither a positive nor a negative charge). Atoms' nuclei are made up of protons and neutrons. Protons and neutrons are both referred to as nucleons because of how similarly they function inside the nucleus and because they both have masses that are about equal to one atomic mass unit. Nuclear physics describes their characteristics and interactions.

The arrangement of electrons around an atom's hefty nucleus largely determines its chemical characteristics. The amount of protons, or atomic number, determines the charge of the nucleus, which determines the electron configuration.
