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.
Alkali metals lose one electron when it becomes an ion.
An iron atom typically becomes a positively charged ion, known as Fe2+ or Fe3+, by losing electrons to achieve a stable electron configuration.

No, sodium is stable by losing 1 electron in order to achieve a full outer electron shell and become a positively charged ion called Na+.
Calcium loses its two valence electrons to become Ca 2+ ion.
Hydrogen becomes an ion in chemical reactions by losing its single electron, leaving behind a positively charged hydrogen 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.
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
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.
Some molecules can become ions, especially at very high temperatures or at other high-energy conditions. For example, a hydrogen molecule can become a positive ion by losing one of its electrons.
An atom can become an ion by either gaining or losing electrons. If it gains electrons, it becomes an anion. If it loses electrons, it becomes a cation. An ion is merely an atom with a charge, either positive or negative.
Alkali metals lose one electron when it becomes an ion.
These elements are the alkali metals.
Because they are either losing or gaining an electron
a. gaining an electron to form a negative ion. Halogens are highly reactive nonmetals that typically gain one electron to achieve a full outer electron shell, forming a negative ion.
