An atom can become positive if it loses an electron. For example if the atom had five protons and five electrons, then loses an electron, it would have more protons making it more positive than negative.
This atom become a cation (positive charge).
If a fluorine atom were to attract an extra electron from a lithium atom, the lithium atom would become a positive charge because it loses an electron.
If a fluorine atom were to attract an extra electron from lithium, the lithium atom would become a positive charge. This is because it would lose an electron, leaving it with a net positive charge due to the loss of a negatively charged electron.
A positive ion can become a neutral atom by gaining electrons. When a positive ion gains one or more electrons, it becomes neutral because the negative charge of the electron(s) cancels out the positive charge of the ion.
Gaining an electron that has a negative charge would negatively charge the atom.
This atom become a cation (positive).
The stability of the positive ion depends on the atom which removes the electron. As an example, when a sodium atom becomes positive, it is highly stable, on the contrary, when a chlorine atom becomes positive, it is highly unstable.
it becomes positive
This atom become a cation (positive charge).
The atom gets negative charges and positive charges from other things.
metal atoms
When the neutral atom of sodium lose an electron become the cation Na+.
A neutral atom becomes a positive atom by losing an electron.
Positive ions form when an atom or group of atoms loses one or more electrons.
Ions (atoms that have lost or gained electrons) can make an atom become positive (a cation) or negative (a anion). When an atom loses an electron it becomes positive since there are more protons (positively charged particles) than there are electrons (negatively charged particles) at that point. When an atom gains an electron it becomes negative because there are more electrons than are protons at that point.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
When an atom lose electrons become a cation (positively charged).
