Question

match terms with the correct definition.
column a

1. atomic number
2. atomic mass
3. proton
4. neutron
5. electron
6. valence electrons

column b
a. positively charged particles located in the nucleus of an atom
b. equal to the number of protons in an atom
c. negatively charged particles surrounding the nucleus of an atom
d. outermost electrons of an atom that deal with bonding
e. equal to the number of protons and neutrons in an atom
f. particles with no charge located in the nucleus of an atom

Explanation:

1. Atomic Number: It is defined as the number of protons in an atom, so it matches with b.
2. Atomic Mass: It is equal to the sum of the number of protons and neutrons in an atom, so it matches with e.
3. Proton: Positively - charged particles located in the nucleus of an atom, so it matches with a.
4. Neutron: Particles with no charge located in the nucleus of an atom, so it matches with f.
5. Electron: Negatively - charged particles surrounding the nucleus of an atom, so it matches with c.
6. Valence Electrons: Outermost electrons of an atom that deal with bonding, so it matches with d.

Answer:

1. Atomic Number - b
2. Atomic Mass - e
3. Proton - a
4. Neutron - f
5. Electron - c
6. Valence Electrons - d
