th vocabulary word to its definition.

atomic particle that has mass but no charge

atomic particle that has positive charge and mass

ber of protons in an atom

al number of protons and neutrons in an atom

atomic particle that has a negative charge but no mass

Explanation:

1. For "atomic particle that has mass but NO charge", the correct match is Neutron (neutrons have mass and are neutral).
2. For "atomic particle that has POSITIVE charge and mass", the correct match is Proton (protons have positive charge and mass).
3. For "number of protons in an atom", the correct match is Atomic number (atomic number is defined as the number of protons in an atom's nucleus).
4. For "total number of protons and neutrons in an atom", the correct match is Mass number (mass number is the sum of protons and neutrons).
5. For "atomic particle that has a NEGATIVE charge but no mass", the correct match is Electron (electrons have negative charge and negligible mass compared to protons and neutrons).

Answer:

1. atomic particle that has mass but NO charge - Neutron
2. atomic particle that has POSITIVE charge and mass - Proton
3. number of protons in an atom - Atomic number
4. total number of protons and neutrons in an atom - Mass number
5. atomic particle that has a NEGATIVE charge but no mass - Electron
