A positive ion (cation) is formed by removing electron(s) from an atom or group of atoms until there are fewer electrons than protons.
A negative ion (anion) is formed when an atom or group of atoms gains electron(s) until there are more electrons than protons.
Only non-metals form negative ions - this ability (to gain electrons) is intrinsic to the nature of non-metals.
Only metals form positive ions - this ability (to lose electrons) is intrinsic to the nature of metals.
A polyatomic ion is a group of atoms with a charge.
Yes, the cation is a positive ion; ex.: H+, Ca2+, (UO2)2+.
Negative charge: electrons Positive charge: protons
Molecules that carry positive or negative electrical charges are called ions. Positively charged ions are called cations, while negatively charged ions are called anions. Ions are formed when atoms gain or lose electrons.
No, copper typically forms positive ions by losing electrons to achieve a stable electron configuration. Negative ions are formed by gaining electrons.

A polyatomic ion is a group of atoms with a charge.
Positive ions are formed when an atom loses electrons, resulting in a net positive charge. Negative ions are formed when an atom gains electrons, resulting in a net negative charge. In chemical reactions, ions can be identified based on their charge and presence of a positive or negative sign.
A negative ion (anion) is formed after gain of electrons in the atom.A positive ion (cation) is formed after loss of electrons from the atom.
When positive and negative ions attract each other, an ionic bond is formed. Ionic bonding refers to the complete transfer of valence electron between atoms.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Yes, the cation is a positive ion; ex.: H+, Ca2+, (UO2)2+.
positive ions carry positive charge and negative ions carry negative charge
B. negative ions. Negative ions are formed when neutral atoms gain electrons, increasing their size due to the additional electron(s) while positive ions or cations are formed when neutral atoms lose electrons, reducing their size.
Ions can have either a positive or a negative charge.
An ionic solid. More specifically, the alternating positive and negative ions form an ionic lattice.
