A nuclear reaction of some sort ( not necessarily violent blast). there are various Isotopes of some elements- with differing atomic numbers.
The type of atom is now different from what it was. (It has a new identity.)
What differentiates one element from another (like Hydrogen from Helium) is the number of protons in the nucleus. When protons are added (as happens in nuclear fusion) or subtracted (nuclear fission), the element transmutes into another element. When the number of Protons are changed, both the Electrons and Neutron (numbers) will change too. Protons are paired with electrons. Protons + Electrons = Neutrons, thus reinforcing that both the Electrons and Neutrons will change when the number of Protons has.
no isotopes of a particular chemical element all have the same number of protons
The number of protons must be the same for the neutral isotopes and for the ions of a given element. A change of the number of protons would change the atomic number and the identity the chemical species.
You would have a different element. This is not something that is easy to do in practice. It's nuclear physics, not something that happens in the test tube.

The element transforms itself into another element because each element have a specific number of protons. If the number of protons changes, the element changes as well. The number of protons in an atom defines it elemental identity, so if the number of protons in an element increases by one it becomes another element. Although this reference doesn't really provide a direct answer, it does provide additional information that might be of interest: http://www.answers.com/topic/proton
Yes. Atoms with a different number of neutrons are called isotopes of that atom, but a variation in the number of neutrons does not change what the atom is.

The element becomes a new element becuase the atomic number would change. For example if you added a proton to Hydrogen-atomic number 1, it would become helium-atomic number 2

If an atom were to change the number of protons it had than it would change the atomic number and therefore become a different element. Radioactive decay is one example of this, for example, alpha decay is when a radioactive nucleus emits an alpha particle (2 protons + 2 neutrons) and in doing so, becomes a nucleus of a different element. Polonium-212 decays to Lead-208 in this way.
The mass number would be different for different isotopes of the same element.
No it NEVER EVER EVER EVER changes other wise it would be a completely different element like aluminum .
No. In both the cases the element would definitely change. As alpha particle comes out then the new element would have two less in atomic number where as in beta particle decay the new element will have one higher in atomic number.
Atomic numbers are determined by the number of protons an atom has. The mass number is determined by the number of protons and neutrons. While the number of protons can't change (as the element itself would change), neutrons can and do vary. These are called isotopes.
Transmutation by definition means the conversion of one element into another, and so it follows that its atomic number must also change. Every element has a unique atomic number.
