Electrons have a negative charge, so they are usually written as "e-". When an atom loses an electron, the net charge on the atom increases.
Suppose a hydrogen atom is hanging out (note that hydrogen is diatomic, but ignore that part for now) and somehow loses its electron. The electron will get taken up by something else with a positive charge (opposite charges attract each other). In general it would look something like the following:
H -> H+ + e-
This positively charged hydrogen (H+ on the products side) is considered a Cation (cation's are positive as they have a T in them that looks like a +, anions don't have a T so they are what we call negatively charged anions).
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
An atom becomes charged when it either gains or loses one or more electrons. If an atom gains electrons, it becomes negatively charged (anion); if it loses electrons, it becomes positively charged (cation). This process is known as ionization.
If an atom gains or loses electrons, it becomes an ion. If it gains electrons, it becomes a negatively charged ion called an anion. If it loses electrons, it becomes a positively charged ion called a cation.
A neutral atom that gains or loses electrons is now an ION. If it loses electrons to become M^(n+), then it is a CATION. If it gains electrons to become X^(n-), then it is an ANION. NB Atoms that gain or lose electrons are no longer atoms , but IONS.
When an atom gains electrons, it becomes negatively charged because it now has more electrons than protons. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.

An ion is formed when an atom gains or loses an electrons or electrons. If it gains an electron, it becomes an anion, and if it loses an electron it becomes a cation.
This neutral atom become a cation or an anion.
When an atom loses or gains electrons, it becomes an ion.
it becomes an ion
An atom is electrically neutral; it has the same number of positively charged protons as it has negatively charged electrons. If an atom either gains or loses one or more electrons, then it will have an electric charge, and will be an ion.
A neutral atom that gains or loses electrons is now an ION. If it loses electrons to become M^(n+), then it is a CATION. If it gains electrons to become X^(n-), then it is an ANION. NB Atoms that gain or lose electrons are no longer atoms , but IONS.
This single atom remain an atom of krypton !
When an atom gains electrons, it becomes negatively charged because it now has more electrons than protons. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
