Periodic Trends

Front

What is electronegativity?

Back

Electronegativity is how good an atom is at attracting electrons.

Front

Which atom has the largest atomic radius in Group 18?

Back

The atom with the largest atomic radius in Group 18 is Rn (Radon).

Front

Which atom has the largest atomic radius: potassium, rubidium, francium, or cesium?

Back

Francium has the largest atomic radius.

Front

Which has the greater electronegativity: Cl or Al?

Back

Cl (Chlorine) has the greater electronegativity.

Front

What do atoms with high electronegativity do with their electrons?

Back

Atoms that have a high electronegativity hold on to their electrons more tightly.

Front

Define 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 in the periodic table.

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 the relationship between atomic size and electronegativity?

Back

Generally, as atomic size increases, electronegativity decreases.

Front

What is the most electronegative element?

Back

Fluorine (F) is the most electronegative element.
