Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of the periodic table in chemistry?

Back

It organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is the general trend of electronegativity in the periodic table?

Back

Electronegativity increases across a period and decreases down a group.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
