a neutral atom contains the same amount of protons as electrons
Two 'Down Quarks' and an 'Up Quark' These are Fermions and their different varieties were named by Murray Gel Mann. There is a much fuller explanation in 'What is a neutron'
Equal number of protons and electrons
The barium atom (neutral) contain 56 electrons.

The neutral iodine atom contain the same number of electrons as protons - 53.
18 electrons
A neutral atom must contain an equal number of electrons because it is a neutral atom.
The barium atom (neutral) contain 56 electrons.
Neutral atom of magnesium has 12 electrons.

The neutral iodine atom contain the same number of electrons as protons - 53.
The atom is composed of 3 parts. The pronton (positive), the neutron (neutral) and the electron (negative).
