A neutral atom of Cobalt (Co) has an atomic number of 27 and an atomic mass of 59. Therefore, Co has

A neutral atom of Cobalt (Co) has an atomic number of 27 and an atomic mass of 59. Therefore, Co has 27 electrons, 27 protons and 32 neutrons.

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

The atomic number Co is 27 it means it has 27 protons and 27 electrons.

The mass number is sum of protons and neutrons, thus number of neutrons are

59 - 27 = 32 neutrons

if you mean hydrogen and oxygen then water is the product
