No atoms have a -1 charge, but the group that has 7 electrons and needs to gain 1 more would be the Halogens: Fluorine, Chlorine, Bromine, Iodine, and Astatine
Since electrons are negative, they get a negative charge.
A chemical bond with unequal sharing of electrons is called a covalent bond. This results to a slightly negative charge on one end and a slightly positive charge on the other end.
A charge which is not a positive charge is a negative charge.
Electrons have a negative charge. Protons have a positive charge, and neutrons have a neutral charge. Added: Electrons always have a negative charge, value: minus 1.602*10-19 Coulomb.
No. Electrons possess a negative charge, therefore an atom with an excess of electrons will have an overall negative charge.
Electrons charge is a negative
Electrons have a negative charge. When an element had more electrons than protons, it tends to have a negative charge.
The negative sign implies that chlorine has gained an electron, which chlorine will easily do in a chemical reaction. The negative charge means the electrons now outnumber the protons 18-17, hence the negative 1 charge. (remember, electrons are negative.)
They do have a charge, it's negative
only the electrons have a negative charge but they go around the nucleus
Yes, calcium has valence electrons - two, in fact (it is a divalent chemical element).
Electrons have an electrical negative charge.
Pprotons have a positive charge neutrons have no charge and electrons have a negative charge. However the one with the smallest mass is electrons.
I think you mean what are the main parts of a chemical atom. There are three particles: protons (which have a positive charge), electrons (a negative charge) and neutrons (no charge).
