What are valence electrons?

Back

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

Front

What types of atoms typically form covalent bonds?

Back

Covalent bonds are typically formed between two nonmetals.

Front

Back

Lithium should have 1 electron around its Lewis dot model.

Front

What is a covalent bond?

Back

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

Front

What is the difference between a covalent bond and an ionic bond?

Back

A covalent bond involves the sharing of electrons, while an ionic bond involves the transfer of electrons from one atom to another.

Front

What is a Lewis dot structure?

Back

A Lewis dot structure is a diagram that shows the bonding between atoms and the lone pairs of electrons in a molecule.

Front

What is the significance of the octet rule in covalent bonding?

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.
