an atom becomes a cation when the atom loses electrons during a reaction, and it becomes an anion when the atom gains electrons in a reaction it accepts an additional electron.

Atoms become cations when they lose (a) negatively charged electron(s). Once the atoms loses (an) electron(s), it becomes positively charged because it has more positive protons than negative electrons.

An element can become a cation by loosing electrons and an anion by gaining electrons.

For example:-

Na(Sodium) atom has 11 electrons whereas its cation Na+ has 10 electrons.

Cl(chlorine) atom has 17 electrons but its anion Cl- has 18 electrons.

The element will form a cation or anion will be decided by the no. of electrons in its outermost shell.

Metals generally form cations and non-metals generally form anions.

However, some elements like carbon do not form ions at all and form their bonds by sharing electrons.

How does an ion become a cation?

any atom lose one electron or more become positive ion ( Cation ) Dont really get your question:( BY definition, an atom that has lost or gained an electron meaning its a charged particle. A cation is an atom that has lost electrons to form a positively charged atom meaning that a cation is an ion. However, an anion also falls under the definition of an ion ( An anion is an atom that has gained an electron to form a negatively charged particle) In that case, it will need to lose electrons to form a cation(positively charged particle.) Not sure if you are referring to that though hope that helps:DD


Is tin cation or anion?

Tin itself is a neutral element and therefore neither a cation nor an anion. A single tin atom can form a cation by donating two or four of its electrons to more electronegative atoms. A single tin atom is not electronegative enough to form an anion, but together with oxygen atoms, a tin atom can form a polyatomic anion.


What does an atom that has lost or gained an electron become?

Generically an "ion", specifically gained an electron an "anion", lost and electron a "cation".

What is a charged atom?

A charged atom is an ion. A positively charged version is a cation and a negatively charged one, an anion.


How does a cation differ from an anion?

A cation is a type of an ion, or a charged atom. An atom is the main module. They have the same number of protons and electrons. An ion has a different number between the two. A cation is just an atom with fewer electrons than protons.


What is an atom called after an ionic bond?

Ions. And they can also be called anion or cation depending on their charges. An anion is a negative ion, a cation is a positive ion.
