Gold, like all metals, loses electrons when it ionizes, but also note that it is very difficult to ionize gold.
Calcium loses its two valence electrons to become Ca 2+ ion.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.
Alkali metals lose one electron when it becomes an ion.

Sodium can become stable by losing 1 electron, forming a sodium ion with a 1+ charge, with the formula Na+. By losing its single valence electron, the resulting sodium ion achieves the noble gas configuration of neon, so that it has an octet (8) of valence electrons.
Calcium loses its two valence electrons to become Ca 2+ ion.
If the atom was not a negative ion prior to losing an electron, it becomes a positive ion.
Since electrons are negatively charged, losing an electron will make the hydrogen atom become a positively charged ion.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
It can be positive or negative depending on if the atom loses or gains an electron. If it gains an electron it becomes negative and if it loses an electron it becomes positive.
A: Gaining an electron
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.
Because they are either losing or gaining an electron
The H+ ion has a positive charge because it has lost one electron. Since hydrogen has only one electron in its base state, H+ has no electrons. The positive charge of the ion occurs because the hydrogen atom has lost an electron. Electrons are negatively charged particles; therefore, losing an electron causes the hydrogen atom to become more positive (less negative) than before.
Electrovalence is a another word for somthing that has given up its electron and become an ion.
