In other words, the number of neutrons in any atom is its mass number minus its atomic number. Number of neutrons = mass number - atomic number or Mass number = number of protons + number of neutrons
WebThe chemistry of the atom is associated with its electron distribution. The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom. This is known as the atomic number, Z. The removal or addition of electrons to a neutral atom creates ions that have a net negative or positive charge.
