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)

100 dollars because yeah

hope it mark me as brainlieast.
