Determining the Number of protons, neutrons and electrons in an ATOM

This video tutorial explains how to use the periodic table to determine the number of protons, neutrons, and electrons in an atom. It covers the basic structure of atoms, the significance of atomic number and mass, and provides examples using elements like oxygen, magnesium, calcium, and zinc. The tutorial emphasizes the relationship between protons and electrons in neutral atoms and demonstrates how to calculate the number of neutrons using mass number.

What is the formula for calculating the number of neutrons in an atom?

Using the example of magnesium, how do you find the number of neutrons given the mass number?
