Define electron configuration.

Back

Electron configuration is the distribution of electrons in an atom's orbitals.

Front

What is the significance of the periodic table in chemistry?

Back

The periodic table organizes elements based on their atomic number, electron configurations, and recurring chemical properties.

Front

What is the difference between metals, nonmetals, and metalloids?

Back

Metals are conductive and malleable, nonmetals are poor conductors and brittle, and metalloids have properties of both.

Front

What is the role of valence electrons in chemical bonding?

Back

Valence electrons are involved in forming bonds between atoms, determining the chemical reactivity of an element.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
