Why are the number of protons and electrons equal in an atom?

Actually the proton and electron count of an atom are equal only when the atom is neutral in charge. The three atomic particles of an atom are the protons, which carry a positive charge, the electrons which carry a negative charge and the neutrons which have no charge.

Moreover, are number of protons and electrons the same?

The number of protons in the atom of an element determines its place in the periodic table. The number of electrons in an atom is the same as the number of protons. These electrons are arranged in shells or 'energy levels' around the nucleus.

Do protons always equal neutrons?

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Why are there always equal numbers of protons and electrons in an atom?

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
