Chemical Bonds

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

The two main types of chemical bonds are ionic bonds and covalent bonds.

An ionic bond is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of charged ions.

A covalent bond is a type of chemical bond that involves the sharing of electron pairs between atoms.

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

The number of valence electrons can be determined by the group number of the element in the periodic table.

The periods in the periodic table indicate the number of energy levels in the electron cloud of the elements.

A molecule is a group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.

A compound is a substance formed when two or more different elements are chemically bonded together.
