To find the number of neutrons in an atom, you would need to know the atomic number and the mass number of the element. The atomic number represents the number of protons in the nucleus, while the mass number represents the total number of protons and neutrons combined.

Here’s a step-by-step process to find the number of neutrons:

  1. Identify the atomic number: The atomic number is usually represented by the letter “Z” and can be found on the periodic table. It is the whole number located above or below the elemental symbol.

  2. Identify the mass number: The mass number is usually represented by the letter “A” and can also be found on the periodic table. It is the decimal number located above or below the elemental symbol.

  3. Subtract the atomic number from the mass number: The difference between the mass number (A) and the atomic number (Z) gives you the number of neutrons (N). Mathematically, it can be represented as N = A - Z.

For example, if we take the element carbon, which has an atomic number of 6 and a mass number of 12. To find the number of neutrons in carbon, we subtract the atomic number from the mass number: N = 12 - 6 = 6. Therefore, carbon has 6 neutrons.

This method can be used for any element to determine the number of neutrons present in its nucleus.
