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.

Electrons and protons.
Proton and neutron.
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.
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.
protons and electrons
Protons and Electrons. Protons are positively)+) charged and electrons (-) are negatively charged. For an atom to be neutrally charged the number of protons MUST equal the number of electrons. The number of positives must equal the number of negatives. When these number are NOT equal ; loss/gain of electrons, then the atom is named an ION.
There are more than two particles in a carbon atom. There are two TYPES of particles, which are protons and neutrons. There are six protons, and 16 known amounts of neutrons Check here for info on the number of neutrons: http://en.wikipedia.org/wiki/Isotopes_of_carbon
