What is mass number of an atom?

The sum of the total number of electrons and protons in an atom is called the mass number of the atom. It is denoted as A. Mass number is always a whole number. A neutral atom contains an equal number of electrons and protons.

How to Calculate Mass number?

Mass number calculator uses Mass number=Number of Protons+Number of Neutrons to calculate the Mass number, The Mass number is the sum of the number of protons and neutrons in an atom of an element. It is also called a nucleon number. Mass number and is denoted by A symbol.

How to calculate Mass number using this online calculator? To use this online calculator for Mass number, enter Number of Protons (p+) and Number of Neutrons (no) and hit the calculate button. Here is how the Mass number calculation can be explained with given input values -> 12 = 6+6.

FAQ

What is Mass number?
The Mass number is the sum of the number of protons and neutrons in an atom of an element. It is also called a nucleon number and is represented as A=p++no or Mass number=Number of Protons+Number of Neutrons. The number of protons is the total number of positive subatomic particles found in the nucleus and The number of neutrons is the total number of neutral subatomic particles found in the nucleus.
How to calculate Mass number?
The Mass number is the sum of the number of protons and neutrons in an atom of an element. It is also called a nucleon number is calculated using Mass number=Number of Protons+Number of Neutrons. To calculate Mass number, you need Number of Protons (p+) and Number of Neutrons (no). With our tool, you need to enter the respective value for Number of Protons and Number of Neutrons and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
