Answer:
1. Alpha
2. Positron
3. Electron
4. Neutrino
5. Proton
6. Meson
7. Neutron
8. Beta
9. Gamma
Explanation:
1. made of two protons and two neutrons alpha ( It is helium atom that has no electron or it is just a helium nucleus with two protons and two neutrons)
2. similar to an electron; positive charge positron ( it is the antiparticle or antimatter just opposite to electron in charge, rest all properties are similar to electron)
3. orbits nucleus; negative charge electron ( Electron is found outside the nucleus of an atom and it is only the subatomic particle that is responsible for negative charge in an atom)
4. bundle of energy; zero charge neutrino ( It is an antiparticle or antimatter just like an electron but charge equal to zero)
5. found in nucleus; positive charge proton ( A nucleus of an atom has two sub atomic particles one is proton (with a positive charge) and a neutron (with a neutral charge)
6. very unstable; +, -, or zero charge meson ( Meson is considered as a hadronic particles which are found with in an atom and are made up of one quark and one antiquark bounded by strong inter particle forces
7. found in nucleus; zero charge neutron ( A nucleus of an atom has two sub atomic particles one is proton (with a positive charge) and a neutron (with a neutral charge)
8. negative particle; negative charge beta ( These are high speed electron released during an atomic decay process.)
9. atomic energy converted to mass gamma ( These are energetic electromagnetic radiation released during atomic decay)
