One way to predict the type of bond that forms between two elements is to consider whether each element is a metal or nonmetal. In general, covalent bonds form between nonmetals, ionic bonds form between metals and nonmetals, and metallic bonds form between metals.

Lewis diagrams (or Lewis structures) are models that show how atoms are bonded together in a molecule and the arrangement of valence electrons around the atoms in that molecule. They provide a visual representation that helps us understand molecular bonding, visualize molecular shapes, and predict chemical reactivity.

Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O).

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. For example, KCl, an ionic compound that contains K⁺ and Cl⁻ ions, is named potassium chloride. View more lessons or practice this subject at https://www.khanacademy.org/science/c...

When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.
