The atoms located on the left side of the Periodic Table, like elements such as lithium, sodium, potassium, caesium, rubidium and francium. These elements lose an electron very easy. The common name of these is alkaline metals.
But not only alkaline metals lose electrons easily. A basic rule is that elements located on the left side of the Periodic Table loses electrons, and those on the right side gets electrons.
I'll try to explain this very fast. The periodic table is organized very well. Which number the element is tells you how many protons the atom has. The atom has as many electrons as protons.
When we're talking about reactions between elements, the outer shell of electrons is important. The electrons of the atom are organized very well, in several "shells". Which horizontal line the element is placed on tells you how many shells the atom has, and the vertical line tells you how many electrons it has in the outer shell.
What the atoms "want" in a reaction is to have full outer shells. The atoms located on the left side has very fewelectrons in the outer shell, and the atoms on the right has very many electrons in the outer shell. Therefore, the atoms on the left gives away electrons, and the ones on the right get electrons. This is also why the atoms located on the middle of the periodic table don't react so easily, and why the atoms on the very right side (the noble gases) don't react at all.
lose electrons and form cations.
Beryllium tends to lose two electrons to form a 2+ cation.
Atoms will form an ionic bond when one atom donates an electron to another atom. Typically, this occurs between a metal atom (which tends to lose electrons to form positive ions) and a non-metal atom (which tends to gain electrons to form negative ions).
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
Ionic bonds form in an ionic compound when one atom transfers electrons to another atom, resulting in the formation of positively and negatively charged ions. The opposite charges attract each other, creating a strong electrostatic force that holds the ions together in a stable structure. This transfer of electrons occurs between a metal atom (which tends to lose electrons) and a nonmetal atom (which tends to gain electrons).
The kind of atom that likes to be oxidized.

An atom with single electron in its outermost shell
Atoms will form an ionic bond when one atom donates an electron to another atom. Typically, this occurs between a metal atom (which tends to lose electrons to form positive ions) and a non-metal atom (which tends to gain electrons to form negative ions).
An atom that tends to lose one electron typically has fewer electrons than protons in its nucleus. These atoms are usually found in Group 1 or Group 2 of the periodic table, such as elements like sodium or magnesium. When they lose one electron, they form positively charged ions called cations.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
A metal atom tends to lose electrons to form a positively charged ion, known as a cation. The number of electrons lost is equal to the atom's valence electrons, which results in a full outer shell and increased stability.
Ionic bonds form in an ionic compound when one atom transfers electrons to another atom, resulting in the formation of positively and negatively charged ions. The opposite charges attract each other, creating a strong electrostatic force that holds the ions together in a stable structure. This transfer of electrons occurs between a metal atom (which tends to lose electrons) and a nonmetal atom (which tends to gain electrons).
Atoms lose electrons to form positively charged cations.
A calcium atom tends to lose two electrons. This is because calcium has two electrons in its outermost shell (the fourth period of the periodic table), and it typically seeks to achieve a stable electron configuration by losing these two valence electrons. As a result, calcium commonly forms a +2 cation (Ca²⁺) in chemical reactions.
An ionic bond is formed through the transfer of electrons from one atom to another. This transfer occurs between a metal atom (that tends to lose electrons) and a nonmetal atom (that tends to gain electrons). The resulting attraction between the positively charged metal cation and the negatively charged nonmetal anion forms the ionic bond.
