Is calcium oxide a positive or negative ion?
Calcium oxide is a compound composed of calcium (Ca) and oxygen (O) ions. Calcium has a 2+ charge, while oxygen has a 2- charge. Therefore, calcium oxide is made up of a positive calcium ion (Ca2+) and a negative oxide ion (O2-).
What kind of charge does oxygen have positive or negative?
Oxygen typically has a negative charge when it forms ions, such as in the case of the oxide ion (O2-). In its neutral state, oxygen atoms do not have a net charge.
How is a positive ion different than ion?
A positive ion has lost one or more electrons, giving it a net positive charge, while an ion can be either positive (cation) or negative (anion) depending on if it has gained or lost electrons.
What charge does an ion have if it has more protons then electrons?
The ion would have a positive charge if it has more protons than electrons. Since protons have a positive charge and electrons have a negative charge, an excess of protons will result in an overall positive charge for the ion.
Does an ion have a charge?
Yes, an ion is an atom or molecule that has gained or lost electrons, resulting in a positive or negative charge.
