Cations are positive ions, so an atom is supposed to lose electrons to become a cation. Anions are formed when an atom gains electrons.
An ion is produced when an atom or a molecule loses or gains electric charge, which is losing or gaining electrons, starting with the outer most level of the electron cloud, which is the most unstable.Ions differentiate into anions and cations. Anions are those which gained electrons and are negatively charged, while cations are those which lost electrons and are positively charged.Anions and cations combine with each other to form stable molecules and new substances.B.Anode
When one atom gives up an electron to another atom, it forms an ionic bond. The atom that loses the electron becomes positively charged (cation), while the atom that gains the electron becomes negatively charged (anion).
Ionic bonds do not have valence electrons; rather, they form between atoms by electron transfer where one atom gives up electrons (cations) and the other gains electrons (anions). The resulting ions are held together by electrostatic forces, not by sharing electrons as in covalent bonds.
they form cations
If an atom is electropositive (metals, in general), then they will lose electrons and form positive ions. If an atom is electronegative (non-metals, in general), then they will gain electrons and form negative ions.
they form cations
A cation forms when an atom loses one or more electrons, resulting in a positively charged ion. This loss of electrons leaves the atom with more protons than electrons, creating an overall positive charge.

an atom loses electrons and becomes positivly charged
They are lost. If it has a plus sign beside the ion charge, that means the atom loses electrons. But if it has a negative sign for the ion charge, that means that the atom gains electrons.
The energy change that occurs when an atom gains electrons is called the
When one atom gives up an electron to another atom, it forms an ionic bond. The atom that loses the electron becomes positively charged (cation), while the atom that gains the electron becomes negatively charged (anion).
Ions are formed when an atom gains or loses electrons and gets charged. If an atom gains electrons, number of electrons exceed from the number of proton and hence an atom gets negatively charged. Similarly if an atom looses electrons the total number of protons become more than the number of electrons.. and the atom becomes positively charged.

Atoms lose electrons to form positively charged cations.

NoMetals are found on the left side of the periodic table, so they need to lose electrons to be like the noble gases and satisfy the octet rule. When an atom loses electrons, it becomes positive, because electrons are negative.As for knowing whether an anion is positive or negative, you just have to memorize the fact that cations are positive and anions are negative.
