Chemical Bonding

Science

A bond that holds two or more atoms together

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.

A shorthand that uses symbols to represent elements in a compound

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.

The substance made when atoms from two or more elements combine chemically

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.

A chemical bond formed when atoms share electrons

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.

The attraction between oppositely charged ions

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.

A bond formed when metal atoms share electrons

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.

The unequal sharing of electrons in a covalent bond

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.

A solid of ions or atoms arranged in an orderly three-dimensional pattern

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.

An ion made of more than one atom, it may have a positive or negative charge

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.

An electron in the outermost energy level of an atom, it helps form chemical bonds

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.

A number written below and to the right of a chemical symbol

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.

A model that represents an atom’s outside electrons using dots

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.
