Periodic trends review

Front

What is atomic radius?

Back

The atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons. It generally increases down a group and decreases across a period.

Front

Which element has the largest atomic radius among Ca, Be, Ba, and Sr?

Back

Barium (Ba) has the largest atomic radius among these elements.

Front

What charge does an oxide ion carry?

Back

An oxide ion carries a charge of -2.

Front

Which elements have the most similar chemical properties?

Back

Oxygen (O) and sulfur (S) have the most similar chemical properties because they are in the same group of the periodic table.

Front

Which element has a greater need for electrons: chlorine (Cl) or francium (Fr)?

Back

Chlorine (Cl) has a greater need for electrons compared to francium (Fr).

Front

What is the charge of an aluminum ion?

Back

The charge of an aluminum ion is +3.

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 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 electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

Which element is more electronegative: fluorine (F) or iodine (I)?

Back

Fluorine (F) is more electronegative than iodine (I).
