This cannot be shown correctly on Answers. Firstly, if it's charged it's an ion not an atom. The correct notation is symbol then the number as a superscript, then the plus or minus as a superscript.
an ion with a 2- charge has 2 more electrons than usual
A zinc atom typically has a positive charge of +2 due to the loss of two electrons in its outer shell.
2-
Gained 2 electrons
The formal charge of each fluorine atom in GeF6 2- is -1, and the formal charge of the germanium atom is +2. The overall formal charge of the GeF6 2- ion is -2.
The neutral atom of magnesium has no electrical charge; the ion is bivalent.
The overall charge of a carbon atom and three oxygen atoms would be -2. This is because carbon has an oxidation state of +4 and each oxygen atom has an oxidation state of -2, resulting in a total charge of -2 for the entire molecule.
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
2 unbalanced electrons have a 2- charge on the molecule/atom
A helium atom has no electrical charge because it has equal numbers of protons and electrons. The positive charge of the protons is balanced by the negative charge of the electrons, resulting in an overall neutral charge for the atom.
It has a charge of 0.Each potassium atom has a charge of 1+Sulfate has a charge of 2-Also, compounds are generally without a charge.
