Front

What is the trend in atomic radius across a period and down a group?

Back

Atomic radius decreases across a period and increases down a group.

Front

Which of the following is NOT a step in forming an ionic bond?

Back

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom.

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.

Front

What is the general trend of ionization energy across a period?

Back

Ionization energy increases across a period.

Front

What is the significance of the octet rule in chemistry?

Back

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