Positive ions form when an atom or group of atoms loses one or more electrons.
they are ions
metals
have lost electrons
It is possible to make positive ions of nonmetals e.g. oxygen, chlorine, by putting enough energy into them. They normally form negative ions when in a spontaneous reaction.
They become cations, positive ions.
All atoms become positive ions when they lose electrons, and negative when they gain electrons.
Metals. Nonmetals are closer to filling up their outer electron shell so the metals give up their electrons and become positive ions.
That is called a cation. They then have a positive charge.
yes positive ions are faster then negative ions
Lose electrons and become positive ions.
A positive ion, also known as a cation, has a positive nuclear charge. For example, Na+1, Mg+2, and Al+3 are all positive ions, because they tend to give away electrons to have a full eight electrons in its last shell and become stable. O-2, F-1, and I-1 are all anions, negatively charged ions. They tend to gain electrons to have a full eight electrons in its last shell and become stable.
Cations are electrically positive ions
