What is a coordinate covalent bond?

Back

A coordinate covalent bond is a type of bond where both bonding electrons come from the same atom.

Describe Thomson’s plum-pudding model of the atom.

Back

Thomson’s plum-pudding model describes an atom as a positively charged material with negatively charged electrons scattered throughout.

Front

How does the ionic radius of metals compare to their atomic radius?

Back

The ions of metals are smaller than their atoms.

Front

How does the ionic radius of nonmetals compare to their atomic radius?

Back

The ions of nonmetals are larger than their atoms.

Front

What determines the chemical properties of an element?

Back

The chemical properties of an element are largely determined by its number of valence electrons.

Front

Which orbital represents the highest energy level?

Back

The 4s orbital represents the highest energy level.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons are significant because they are involved in forming bonds between atoms.

Front

What is the 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 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 is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.
