Chemical Bonding

Chemical bond

A bond that holds two or more atoms together. Chemical bond. A chemical bond is a connection between atoms allowing them to form compounds.

Chemical formula

A shorthand that uses symbols to represent elements in a compound. Chemical formula. A chemical formula shows the types and numbers of atoms present in a molecule.

Compound

The substance made when atoms from two or more elements combine chemically is called a compound. In simple terms, a compound is a substance formed when different elements join together.

Covalent bond

A chemical bond formed when atoms share electrons. Covalent bond. A covalent bond is when two atoms stick together by sharing some of their outer electrons.

Crystal

A solid of ions or atoms arranged in an orderly three-dimensional pattern. A crystal is a material where particles are arranged in a structured, repeating pattern, giving it unique shapes.

Electron dot diagram

A model that represents an atoms outside electrons using dots. Electron dot diagram. It is a simple diagram that shows the valence electrons of an atom as dots around the element's symbol.

Ionic bond

The attraction between oppositely charged ions. Ionic bond. An ionic bond is a strong connection formed when one atom donates an electron to another atom, resulting in positively and negatively charged ions that stick together.

Metallic bond

A bond formed when metal atoms share electrons. Metallic bond. A metallic bond is when metal atoms pool their electrons, allowing them to move freely and create a strong, flexible connection.

Polar bond

The unequal sharing of electrons in a covalent bond. Polar bond. A polar bond is a type of covalent bond where electrons are shared unequally, causing one end to be slightly positive and the other slightly negative.

Polyatomic ion

An ion made of more than one atom, it may have a positive or negative charge. Polyatomic ion. A polyatomic ion is a group of bonded atoms that together have an overall electric charge.

Subscript

A number written below and to the right of a chemical symbol. Subscript. In Science, a subscript indicates the number of atoms of an element in a molecule.

Valence electron

An electron in the outermost energy level of an atom, it helps form chemical bonds. Valence electron. Valence electrons are the outermost electrons of an atom that determine how it reacts with other elements.
