PERIODIC TRENDS

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key factor in determining how atoms interact in chemical bonds.

Front

Which element has the highest electronegativity in the periodic table?

Back

Fluorine (F) has the highest electronegativity in the periodic table.

Front

What is the trend of electronegativity across a period in the periodic table?

Back

Electronegativity increases across a period from left to right due to increasing nuclear charge.

Front

What is the trend of electronegativity down a group in the periodic table?

Back

Electronegativity decreases down a group due to increased distance between the nucleus and the valence electrons.

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the trend of atomic radius across a period?

Back

Atomic radius decreases across a period from left to right due to increasing nuclear charge pulling electrons closer to the nucleus.

Front

What is the trend of atomic radius down a group?

Back

Atomic radius increases down a group due to the addition of electron shells.

Front

Which element has the largest atomic radius among the alkali metals?

Back

Francium (Fr) has the largest atomic radius among the alkali metals.

Front

What is the relationship between electronegativity and ionization energy?

Back

Generally, as electronegativity increases, ionization energy also increases because atoms that attract electrons strongly also hold onto their own electrons tightly.

Front

What is the significance of the octet rule in relation to electronegativity?

Back

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