Front

What is an ionic bond?

Back

A bond formed between two atoms when one atom donates an electron to another, resulting in opposite charges that attract.

Front

What is a covalent bond?

Back

A bond formed when two atoms share one or more pairs of electrons.

Front

How do you determine the number of valence electrons in an element?

Back

By looking at its group number in the periodic table.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What are the properties of ionic compounds?

Back

They typically have high melting and boiling points, and they conduct electricity when dissolved in water.
