Question

In an atom, number of protons and neutrons are added to obtain

Answer 1

Answer:

We obtain a mass number.

Explanation:

• Each atom has a nucleus, which is made up of two types of particles called protons and neutrons (known collectively as nucleons).
• The atomic number is the number of protons in an atom that indicates the element it is a particle of (and therefore also its chemical properties).
• The mass number refers to the total number of protons and neutrons in an atom's nucleus.
• It is determined by the type of atom (i.e. which element it is) as well as the number of neutrons present in that particular atom.

Conclusion:

In an atom, a number of protons and neutrons are added to obtain a mass number.

Answer 2

Answer: We can find MASS NUMBER by adding number of protons and neutrons.

• An atom consist of nucleons and electrons, in which nucleons are collectively made by two particles called protons and neutrons.
• Mass number is the sum of protons and neutrons present in the nucleus.

• It is denoted by A.
• The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu.
