Ionic Bonding and Transition Metals

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions) that occurs when electrons are transferred from one atom to another.

What is the charge of a magnesium ion after it loses two electrons?

Back

Mg²+ (Magnesium ion with a +2 charge)

Front

What is the correct name for the compound FeCl₃?

Back

Iron III Chloride

Front

Why do transition metals have variable valency?

Back

Transition metals have variable valency because they can lose different numbers of electrons from their outer shells, leading to different charges.

Front

What is the formula for Vanadium (V) fluoride?

Back

VF₅

Front

What happens to metals during ionic bonding?

Back

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

Front

What is the charge of an iron ion in Iron III Chloride?

Back

+3 (Iron ion with a +3 charge)

Front

How do you name a compound with a transition metal?

Back

You must indicate the oxidation state of the transition metal in parentheses after its name.

Front

What is the formula for the compound formed between magnesium and oxygen?

Back

MgO (Magnesium oxide) - Magnesium loses two electrons to form Mg²+ and oxygen gains two electrons to form O²-.

Front

What is the significance of the Roman numeral in Iron (III) Chloride?

Back

The Roman numeral indicates the oxidation state of the iron ion, which is +3 in this case.
