Question

If an atom has 18 protons,17 neutrons,and 19 electrons what is the atom electrical charge?

A +2
B +1
C -2
D-1

Answer 1

D: -1

Step-by-step explanation:

18 protons so +18

19 electrons -19

neutrons dont count there neutral

-19+18= -1

Answer 2

Answer: D: -1

Explanation: All protons have a +1 charge, neutrons are neutral, and electron have a -1 charge. Therefore it can be concluded that if the atom has 18 protons which all have +1 charge and 19 electrons which all have -1 charge, then the atom will have a -1 charge since 18-19=-1
