If an atom has 15 protons 13 neutrons and 18 electrons what is the atom's electrical charge?

Answer 1

the nucleus always has a positive charge. The atom on the other hand in its singular state will have no charge as the electrons negative charge counter the protons positive charge. in this example there will be 31 electrons The element would be Gallium but there are not enough neutrons in your question to even make a viable isotope. Gallium typically has 31 protons and 39 neutrons

Answer 2

Since neutrons have no electric charge protons have positive charge and electrons have negative charge, the net charge is always (number of protons) - (number of electrons, in this instance 15 - 18 = -3.

Answer 3

To get the number of neutrons of an atom you subtract the number of protons from the mass number. So in this case, Phosphorus has 15 protons, 15 electrons and 16 neutrons.

Answer 4

There is no charge. each proton provides 1+ charge and each electron provided -1. In this case you have 15+ and 15- which cancels to give an overall charge of 0

Answer 5

15 because the atomic number is the number of protons in the nucleus

Answer 6

if the element is an atom then its atomic number should be equal to the number of electrons

Answer 7

The charge is negative, -3; this is the phosphide ion P3-.

Answer 8

Neutral. If the number of protons and electrons are the same, then the charge is neutral.
