A cation is a positively charged particle that is attracted to a negative cathode.
Cations are formed when an atom loses an electron to have a full outer shell. Metals usually lose electrons to form a cation. They have a positive charge because the atom now has more protons (positive) than electrons (negative).
Example Na+, Mg2+ , Al3+

For the cation the formula is Cu2+.
A singly charged lithium cation.
H + cation => acid
The cation, Ag+
The chemical formula (not symbol) of potassium bicarbonate is KHCO3.
The cation is the sodium ion Na+.
For the cation the formula is Cu2+.
H + cation => acid
A singly charged lithium cation.
The cation. MgO, for instance.
H + cation => acid
Yes. The ammonium ion has a formula of NH4+ and has a positive charge so it is a cation.
The cation, Ag+
The Roman numeral following the cation tells you the oxidation number of that cation. For example, Cu(ll)chloride tags you it is CuCl2 because the (ll) after Cu indicates an ox. no. of 2+.
The chemical formula (not symbol) of potassium bicarbonate is KHCO3.
NH3 is formula for a basic compound, Ammonia.NH4+ is formula for a basic cation, Ammonium.
The potassium ion (cation) is K+.
