'-3'
It is not an atom, when it is a charged species, but an ION.
15 protons (15+) 18 electrons (18-)
Hence +15 - 18 = -3 The charge.
By the numbers given , this is the element Phosphorus. , which can exhibit a 'P^(-3) ion.
If an atom has 16 protons 15 neutrons, and 18 electrons, the atom's electrical charge is -2. This is because the electrical charge is the number of electrons, which would be -18 because of their charge, added to their protons, or positive 16, which leaves a charge of -2.
yes it is and its valency will be 7 (2,8,7). and it will gain and electron or it would be a non metal
Protons have a +1 charge. Electrons have a -1 charge. Neutrons are neutral, therefore this atom as described will have a -4 charge.
I believe that this ion doesn't exist.

MAMAAAA I DONT WANNA DO ITT WAAAAA
Neutrons: no electrical charge Protons: positive charge Electrons: negative charge
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge
If an atom has 15 protons 12 neutrons and 16 electrons, the neutrons have absolutely nothing to do with the electrical charge. Having one more electron than protons would determine the electrical charge of the atom. The atom would have a charge of -1. The extra electron would give it a negative charge.
They are neutrons, protons and electrons. The neutrons have zero charge, protons have a positive charge and electrons have a negative charge.They are neutrons, protons and electrons. The neutrons have zero charge, protons have a positive charge and electrons have a negative charge.
Atoms consist of protons, neutrons and electrons. Protons have a positive charge. Electrons have a negative charge. And neutrons have no charge at all.
Neutrons: no electrical charge Protons: positive charge Electrons: negative charge
Protons and electrons have an electrical charge.
Protons and electrons are charged particles and neutrons have no charge because they are neutral.
Electrons: Negative Protons: Positive Neutrons: Neutral
Protons have an electrical charge of +1. Neutrons have an electrical charge of 0. Electrons have an electrical charge of -1.
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge.
Neutrons have no charge, protons have a positive charge and electrons have a negative charge.
Protons and electrons both have a positive or negative charge, but neutrons have no charge.
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge
Protons have a positive charge, neutrons have no charge, and electrons have negative charge.Neutrons do not carry an electrical charge:)A proton has a positive charge. Remember, NEUTRon = NEUTRal. Proton = Positive. The electrical charge of a proton is 1.6x10^-19 which is equal and opposite to the electrical charge of an electron which is -1.6x10^-19.

Protons: positive charge Electrons: negative charge Neutrons: without electrical charge
