A nickel atom has an atomic number of 28 and an atomic mass of 59. It has a central nucleus composed of 28 protons and 31 neutrons, surrounded by an electron cloud containing 28 electrons.

What is an atom?

The atom consists of matter that may be split without releasing electrical charges.

It's also the smallest unit of matter with chemical element features. As a result, the atom is the fundamental unit of science.

In the nucleus, proton and the neutron is existing. The condition of the atom to be electrically neutral is that the number of the proton and electron should be the same.

A nickel atom has an atomic number of 28 and an atomic mass of 59. In the nucleus, proton and the neutron is existing,the atom is the fundamental part of the particle.

In that, condition, It has a central nucleus composed of 28 protons and 31 neutrons, surrounded by an electron cloud containing 28 electrons.

Hence, option A is correct.
