What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

What is the octet rule?

Back

The octet rule states that atoms are most stable when they have eight electrons in their outer shell, leading them to gain, lose, or share electrons to achieve this configuration.

How do you determine the charge of an ion?

Back

The charge of an ion is determined by the number of electrons lost or gained by an atom. Metals typically lose electrons and become positively charged (cations), while non-metals gain electrons and become negatively charged (anions).

What is the significance of subscripts in a chemical formula?

Back

Subscripts in a chemical formula indicate the number of atoms of each element present in a compound. For example, in CaF2, the '2' indicates there are two fluoride ions for every calcium ion.

How do you write the formula for an ionic compound?

Back

To write the formula for an ionic compound, combine the symbols of the cation and anion, adjusting the subscripts to ensure the total charge is neutral.
