Answer:
Mass number = 31
Atomic Number = 14
Charge = -4
Explanation:
14 protons
17 neutrons
18 electrons
Mass number = ?
Mass number = protons + neutrons.
[tex]Mass\:number = 14+17\\\\Mass \:number = 31[/tex]
Atomic number = ?
The number of protons = atomic number.
Atomic number = 14
Charge = ?
The charge of an element = number of protons minus the number of electrons.
[tex]Charge=14 -18\\\\Charge = -4[/tex]
