Chemical Bonding

Front

What is a chemical bond?

Back

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

Front

What are the main types of chemical bonds?

Back

The main types of chemical bonds are ionic bonds, covalent bonds, and metallic bonds.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a sea of delocalized electrons that are free to move.

Front

What is the octet rule?

Back

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

Front

What are valence electrons?

Back

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

Front

How do nonmetals typically form ions?

Back

Nonmetals typically gain electrons to form negative ions (anions).

Front

How do metals typically form ions?

Back

Metals typically lose electrons to form positive ions (cations).

What is a dot diagram?

Back

A dot diagram, or Lewis dot structure, is a representation of the valence electrons of an atom, shown as dots around the element's symbol.
