Periodic Table 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 higher electronegativity than arsenic (As)?

Back

Carbon (C) has a higher electronegativity than arsenic.

Front

What is ionization energy?

Back

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

Front

What is ionic radius?

Back

Ionic radius is the size of an atom's ion, which can differ from its atomic radius.

Front

What is atomic radius?

Back

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

Front

Which nonmetal is in period 2 and group 16?

Back

Oxygen (O) is a nonmetal in period 2 and group 16.

Front

How does atomic radius change across a period?

Back

Atomic radius decreases from left to right across a period due to increased nuclear charge.

Front

How does atomic radius change down a group?

Back

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

Front

What is the trend of electronegativity in the periodic table?

Back

Electronegativity increases across a period and decreases down a group.

Front

What is the trend of ionization energy in the periodic table?

Back

Ionization energy increases across a period and decreases down a group.
