This phenomenon is known as the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a stable electron configuration, typically having eight electrons in their outer shell. Attaining a full outer shell makes atoms more stable and less reactive. This stability is often achieved through chemical bonding, such as ionic or covalent bonds, where atoms either transfer or share electrons. Elements that achieve this configuration often resemble the noble gases, which naturally have full outer shells.
One way the electronic structure of group 2 elements (alkaline earth metals) is the same is that they all have two valence electrons in their outermost energy level. This gives them similar chemical properties, such as high reactivity in forming ionic compounds by losing these two electrons.
The ions are held in the lattice by the electrostatic force of attraction between these positive ions and the delocalised electrons. This attraction extends throughout the lattice and is called metallic bonding.
It is the electromagnetic force that holds atoms and molecules together. The protons are positively charged, and the electrons are negatively charged. A fundamental law of electrostatics is that opposite charges attract, as you know. And the protons huddled with the neutrons in the nucleus attract and hold the electrons around them. Further, the negatively charged electrons don't like each other, as you could have easily guessed, and they have to make up some special ways to get along in the electron cloud. This gives rise to the electrons arranging themselves in shells or energy levels. Extending that even further, we see that some atoms want to loan out or borrow electrons to set up conditions in the electron cloud where the electrons are "happy" with the arrangement. And this gives rise to chemical bonding, which is the loaning or borrowing of electrons in ionic bonding, or the sharing of electrons in covalent bonding. In the quantum mechanical universe of the atoms, it is electromagnetics that sets the conditions for structures, both of the atoms themselves, and the molecules they form.
The atom is stable when its outermost shell is full because of the fact that it is "happy" and does not want to bond with other atoms.In other words, it doesnt have room for any more bonds with other atoms.

When an atom gives up one or more electrons to another atom, an ionic bond is formed. Atoms are the basic unit of a chemical element.
Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.
Atoms in compounds can be held together in a few ways, including both polar and non-polar covalent, ionic, coordinate, and a few others. These bonds are called INTRAMOLECULAR bonds, meaning that they are the bonds that hold individual atoms together in a compound, or molecule. ELECTRICAL FORCES HOLD ATOMS TOGETHER; ex. an atom's tendency to have a full valence shell. The atoms share their valence electrons, causing an electric attraction to occur between the atoms, forming what we call a chemical or atomic bond.Atoms and molecules (groups of atoms) attract via electromagnetic forces. Atoms consist of Electrons, Protons (which have positive and negative charge respectively) and Neutrons (which gives the atom mass).The movement of electrons within the atoms and molecules causes a charge. These charges are called electromagnetic forces. Two atoms or molecules which have opposite charges will attract each other and bond during a chemical reaction.

As I understand it, since they have the same number of protons, they tend to attract the same number of electrons. All neutral atoms of the same elements will have the same number of electrons. This gives them similar chemical properties, since the chemical properties are, to a great extent, determined by the outermost electrons.
These are the electrons.
An atom becomes negative by gaining one or more extra electrons, which gives it a net negative charge. This can occur through chemical reactions where atoms either share or transfer electrons with other atoms. Negative ions are also known as anions.
