The atomic number of carbon is 6
It is a negative ion
Cesium is a negative ion.
ion kno
positive (+ is always positive) This means it's an ion, because it's lacking one valence electron
There are two pi bonds.
Sodium, Na, is a group 1 element and generally holds a +1 charge.
It is a positive ion. Its charge is 4+ Edit: This answer is incorrect.
It describes the ion. If it is negative it is an anion.
Na is positive ion,Cl is negative ion
No. The carbonate ion contains only carbon and oxygen. Since it is a negative ion, it must combine with some positive ion. If that positive ion is calcium, you get calcium carbonate.
It could be either. Once a metal produces an ion (an atom with electric charge) it could be positive or negative, depending on number of electrons lost or gained.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
has a charge which can be positive (excess protons) or negative (excess electrons). ... becomes an ion - positive ion if deficient in electrons, negative with an excess of electrons.
An ion. If electrons are in excess over proton then it is negative ion. And if less then positive ion
An ion is either a positive charged or a negative charged atom. Negative ions have one or more extra electrons, and positive ones have one or more electrons not there.
it is a negative and positve ion sweg
Negative ion. Cl-
An ion's charge will be either positive or negative, but not both. The charges are mutually exclusive. A positive ion is called a cation, and a negative ion is called an anion.
