Which of the subatomic particles have mass, which have a charge and what is the charge, and where do these particles reside in the atom?

Protons - have mass 1,67 x 10 (-24) g, positive charge and it is situated in nucleus.

Neutrons - have mass the same like protons, but have no charge and they are placed in nucleus, too.

Electrons - have mass 9,1 x10 (-28) g, negative charge and they are situated in electronic cover.

Protons and electrons have same charge (1,6 x10 (-19) C) but different kinds - protons are positive and electrons are negative.
