An atom can become a positive ion, or a cation (cat-ion), when it ''gives'' away one or more electrons.
An atom becomes a negative ion, or an anion (an-ion), when it gains one or more electrons.
Atoms that do this do not have completely filled valence shells, and are therefore reactive. To become unreactive, they have to either gain or lose electrons to have a filled valence shell and thus gain a noble gas configuration.
Hope you understand! :D
Arsenic must gain 3 electrons to become the As-3 ion.
A sodium atom would lose a electron so it would become a Na+ ion
Its charge lose an negative charge. So it is positively charged. +1
The neutral atom become an ion (cation) with the charge +1.
It depends, a proton if is is positively charged ( +) electron if it is negatively charged ( - )
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
Helium is a neutral atom that has several isotopes and can become an ion.
When an atom loses a negative charge, when it loses an electron, it becomes a positive ion.
it becomes an ion
An atom of Calcium will lose an electron to become a posotive ion.
IONS OS ION ^^A charged atom is called an ion
An atom looses or gains electron to become ion. Ions are +ve and -ve atoms.
Arsenic must gain 3 electrons to become the As-3 ion.
It will become a soft ion.
A sodium atom would lose a electron so it would become a Na+ ion
when an atom loose electron it become negative ion and when it gains electron it become positive ion
IONS OS ION ^^A charged atom is called an ion
