Charges of Metals and Non-metals

Flashcards related to the charges of metals and non-metals, including cations, anions, and specific examples of elements.

Cation

A positively charged ion.

Anion

A negatively charged ion.

Metal Charges

Some metals can have more than one charge, especially group B metals.

Non-metal Charges

Most non-metals typically have one charge, except for hydrogen which can have different charges.

Lithium (Li+)

A cation with a +1 charge.

Sodium (Na+)

A cation with a +1 charge.

Potassium (K+)

A cation with a +1 charge.

Aluminum (Al3+)

A cation with a +3 charge.

Zinc (Zn2+)

A cation with a +2 charge.

Fluoride (F-)

An anion with a -1 charge.

Sulfide (S2-)

An anion with a -2 charge.

Oxide (O2-)

An anion with a -2 charge.

Polyatomic Ion

An ion composed of two or more atoms.

Sulfate

A polyatomic ion with the formula SO4 2-.

Nitrate

A polyatomic ion with the formula NO3-.

Phosphate

A polyatomic ion with the formula PO4 3-.

Hydroxide

A polyatomic ion with the formula OH-.

Ammonium (NH4+)

A cation with a +1 charge.

Copper (Cu)

A metal that can have a +1 or +2 charge.

Iron (Fe)
