Answer:
The answers to your questions are given below
Step-by-step explanation:
For ¹⁴ ₆C:
Mass number = 14
Atomic number = 6
Proton = Atomic number
Proton = 6
Mass number = Proton + Neutron
14 = 6 + Neutron
Collect like terms
Neutron = 14 – 6
Neutron = 8
Charge = 0
Charge = Proton – Electron
0 = 6 – Electron
Collect like terms
0 – 6 = – Electron
– 6 = – Electron
Cancel the negative sign.
Electron = 6
For ³⁵ ₁₇Cl¯
Mass number = 35
Atomic number = 17
Proton = Atomic number
Proton = 17
Mass number = Proton + Neutron
35 = 17 + Neutron
Collect like terms
Neutron = 35 – 17
Neutron = 18
Charge = – 1
Charge = Proton – Electron
– 1 = 18 – Electron
Collect like terms
– 1 – 18 = – Electron
– 19 = – Electron
Cancel the negative sign.
Electron = 19
For ⁴⁰ ₂₀Ca
Mass number = 40
Atomic number = 20
Proton = Atomic number
Proton = 20
Mass number = Proton + Neutron
40 = 20 + Neutron
Collect like terms
Neutron = 40 – 20
Neutron = 20
Charge = 0
Charge = Proton – Electron
0 = 20 – Electron
Collect like terms
0 – 20 = – Electron
– 20 = – Electron
Cancel the negative sign.
Electron = 20
