Unit 5 - Chemical Bonds

Front

What charge does an atom have if it gains two electrons?

Back

-2

Front

What is an atom or group of atoms that has an electric charge called?

Back

Ion

Front

What type of bond involves the sharing of valence electrons?

Back

Covalent bond

Front

Define a valence electron.

Back

An electron that is found in the outermost shell of an atom.

Front

Which type of bond involves the transfer of an electron from one atom to another?

Back

Ionic bond.

Front

What is the primary difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is the role of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms.

Front

What is an example of a molecule formed by covalent bonding?

Back

Water (H2O).

Front

What is an example of a compound formed by ionic bonding?

Back

Sodium chloride (NaCl).

Front

How do ionic bonds typically form between atoms?

Back

Ionic bonds form when one atom donates an electron to another atom, resulting in oppositely charged ions that attract each other.
