Front

If an element has a charge of +3, how many negative ions with a charge of -1 are needed to balance it?

Back

Three negative ions with a charge of -1 are needed to balance a +3 charge.

Front

What is the formula for the ionic compound formed by an element X with a charge of +3 and an element Y with a charge of -1?

Back

Front

What do elements in the same group of the periodic table have in common?

Back

Elements in the same group have the same number of valence electrons.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms and are crucial for understanding reactivity.

Front

How do you determine the charge of an ion?

Back

The charge of an ion is determined by the loss or gain of electrons relative to the neutral atom.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of oppositely charged ions.
