Periodic Table Regents Questions

Front

What is the element with the strongest attraction for electrons in a bond?

Back

Chlorine has the strongest attraction for electrons in a bond due to its high electronegativity.

Front

Which element has the lowest density at standard conditions (298 K and 101.3 kPa)?

Back

Nitrogen has the lowest density at standard conditions.

Front

List the elements in order of increasing electronegativity: K, Ca, Sc.

Back

The order of increasing electronegativity is K (potassium), Ca (calcium), Sc (scandium).

Front

Identify a metal, a metalloid, and a noble gas from the following list: sodium, silicon, argon.

Back

Sodium is a metal, silicon is a metalloid, and argon is a noble gas.

Front

Which Group 15 element is classified as a metal?

Back

Bismuth (Bi) is the Group 15 element classified as a metal.

Front

What is electronegativity?

Back

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

Front

What is the significance of the periodic table in chemistry?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are noble gases and why are they unique?

Back

Noble gases are elements in Group 18 of the periodic table that are characterized by their lack of reactivity due to having a full valence shell.

Front

What is the general trend of electronegativity across a period in the periodic table?

Back

Electronegativity generally increases across a period from left to right.

Front

What is the general trend of electronegativity down a group in the periodic table?

Back

Electronegativity generally decreases down a group in the periodic table.
