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, usually between nonmetals.

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 ionic bonds form?

Back

Ionic bonds form when one atom donates an electron to another atom, resulting in the formation of positively and negatively charged ions.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, leading to a dipole moment, while non-polar covalent bonds occur when electrons are shared equally.

Front

What type of elements typically form ionic bonds?

Back

Ionic bonds typically form between metals, which lose electrons, and nonmetals, which gain electrons.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a bond.

Front

What happens to the electrons in a metallic bond?

Back

In a metallic bond, electrons are shared among a lattice of metal atoms, creating a 'sea of electrons' that allows for conductivity.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be either covalent or ionic.
