Atomic Mass Calculator

Enter the number of protons (Z) and neutrons (N) to calculate the atomic mass

Home > Chemistry > Atomic Mass Calculator

The atomic mass calculator determines the atomic mass in conjunction with its unit and image. For a given element, it's miles the quickest and clean manner to find the mixed mass of proton, electron, and neutron in an atom.

What's Atomic Mass?

Atomic mass accounts for the overall mass of an atom, considering its protons, neutrons, and electrons. it's far expressed within the atomic mass unit (amu) and expressed through the image "U".

However, the electron is 1,836 instances lighter than a proton consequently, their contribution to the overall mass of maximum atoms is minimum.

Atomic Mass formula:

Atomic mass is expressed in atomic mass gadgets (u), additionally called Daltons (Da). An atomic mass unit (Dalton) is 1/12 of the mass of a carbon atom. consequently, the unit of atomic mass is \( 1.66 \times 10^-27 kg \).

Atomic mass (u) = number of neutrons + number of protons

OR

\(\ A = N + Z\)

Where:

  • A = atomic mass number
  • Z = number of protons
  • N = number of neutrons

Why does an Atom want a Neutron?

As we understand the atom has a neutral charge and it require neutrons for some purpose: to feature mass to the nucleus and stabilize it in opposition to the repulsive pressure among definitely charged protons. The atomic mass calculator makes their determinations smooth.

However, all of the advantageous costs are concentrated in the middle of the proton. simply as fees repel, there's a force that attempts to ruin the core or nucleus of an atom. the other of this force is the robust nuclear force that exists among neutrons and protons.

therefore, the full amount of robust nuclear enchantment may be expanded by including neutrons to save you atomic destruction. however, the Mole Calculator helps you to calculate the wide variety of moles of a substance primarily based at the molecular weight and the amount of that cloth.

Steps To Use The Calculator:

The atomic weight calculator determines the atomic mass by the following steps:

Input:

  • Enter number of protons (Z) and number of neutrons (N)
  • Press the "calculate" button

Output:

  • Atomic mass number
  • SI units of atomic mass
  • Atomic Symbol
