Protons and electrons.
An atom has the same number of electrons and protons. Protons are positively charged particles found in the nucleus of an atom, while electrons are negatively charged particles that orbit the nucleus.
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.

Protons and neutrons are the two particles that are in the nucleus of an atom. Electrons orbit around the atom
In each neutral atom of any given element, the numbers of electrons and protons are equal, as the charges in the atom must balance. Only the neutron number may vary amongst atoms of the same element.
Yes, two elements can have the same type of atom if they have the same number of protons. Isotopes are atoms of the same element that have different numbers of neutrons, but the same number of protons.
Alpha particles are emitted from the atom taking with it 2 protons and (I am pretty sure) two neutrons. This will change the atomic number of the atom and the atomic weight.
protons and electrons
No two subatomic particles have the exact same mass. The proton and the neutron, however, come close. Neutrons are heavier than protons by only 2.3 X 10-30 kg.
There're two particles in the atom nucleus (protons and neutrons)
