Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

Which element has the greatest ionization energy: Ga, K, Bi, or As?

Back

As has the greatest ionization energy among these elements.

Front

What is a period in the periodic table?

Back

A period is a horizontal row in the periodic table.

Front

What are the elements in the halogen family?

Back

The halogen family includes elements like fluorine, chlorine, bromine, iodine, and astatine.

Front

Which element has chemical properties most similar to bromine: mercury, krypton, potassium, or fluorine?

Back

Fluorine has chemical properties most similar to bromine.

Front

What happens to the energy of an electron when an atom is in an excited state?

Back

An electron in an excited state has greater energy compared to its ground state.

Front

What is a group in the periodic table?

Back

A group is a vertical column in the periodic table, containing elements with similar chemical properties.

Front

What is the significance of 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.

Front

What are transition metals?

Back

Transition metals are elements found in groups 3-12 of the periodic table, known for their ability to form variable oxidation states.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
