Normally positive. However under the right conditions it could be either, as could anything.
Na is positive ion,Cl is negative ion
In BeF2 the cation is Be2+.
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.
Zinc ion (cation) is positive.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
Na is positive ion,Cl is negative ion
The charge on beryllium (Be) is neutral.
In BeF2 the cation is Be2+.
Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.
it is a negative and positve ion sweg
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.
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.
To become more stable: positive+negative=neutral. Neutral is more stable than positive and/or negative.
Zinc ion (cation) is positive.
negative
when an atom loose electron it become negative ion and when it gains electron it become positive ion
The ion acetate is negative.
