adoni [48]

Atoms will combine with each in order to become more chemically stable  by sharing electron and Compounds are formed between two atoms that have chemical bond that links them together.

In order for molecules and crystals to form, atoms or ions must maintain a long-lasting attraction to one another. Ionic and covalent bonds are formed by the sharing of electrons, while ionic bonds are formed by the electrostatic attraction between two oppositely charged ions. There are "strong bonds" or "primary bonds" like covalent, ionic, and metallic bonds as well as "weak bonds" or "secondary bonds" like dipole-dipole interactions, the London dispersion force, and hydrogen bonding. The strength of chemical bonds varies greatly. By sharing or transferring electrons between the involved atoms, strong chemical bonds are created.

Since opposing electric charges attract, the positively charged protons inside a nucleus and the negatively charged electrons that surround it are drawn to one another. Placing an electron between them
