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 is the most electronegative in the periodic table?

Back

Fluorine (F) is the most electronegative element.

Front

What trend is observed in electronegativity as you move down a group in the periodic table?

Back

Electronegativity decreases as you move down a group.

Front

What trend is observed in electronegativity as you move across a period from left to right?

Back

Electronegativity increases as you move across a period from left to right.

Front

What is atomic radius?

Back

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

Front

What trend is observed in atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases as you move down a group.

Front

What trend is observed in atomic radius as you move across a period from left to right?

Back

Atomic radius decreases as you move across a period from left to right.

Front

What is nuclear charge?

Back

Nuclear charge is the total charge of the nucleus, which is determined by the number of protons.

Front

How does nuclear charge affect atomic size?

Back

As nuclear charge increases, atomic size decreases due to the stronger attraction between the nucleus and electrons.

Front

What is the relationship between atomic radius and ionization energy?

Back

Generally, as atomic radius decreases, ionization energy increases.
