Periodic Trends

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has a smaller electronegativity: Cl or Al?

Back

Al has a smaller electronegativity than Cl.

Front

What is atomic radius?

Back

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

Front

Which element has a larger atomic radius than Gallium (Ga)?

Back

Strontium (Sr) has a larger atomic radius than Gallium (Ga).

Front

Which element has the smallest atomic radius: K, Rb, Fr, or Cs?

Back

Potassium (K) has the smallest atomic radius among these elements.

Front

What happens to atomic radius as you move down the periodic table?

Back

Atomic radius increases as you move down the periodic table due to the addition of energy levels.

Front

Why does atomic radius decrease as you move to the right across the periodic table?

Back

Atomic radius decreases because the atoms have more protons, which increases the positive charge and pulls electrons closer.

Front

What is the trend of electronegativity across a period?

Back

Electronegativity generally increases across a period from left to right.

Front

What is the trend of electronegativity down a group?

Back

Electronegativity generally decreases down a group in the periodic table.

Front

Define ionization energy.

Back

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