ACP REVIEW #4 PERIODIC TRENDS

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 is a measure of the size of an atom.

Front

Which group of elements has the largest atomic radius?

Back

Group 1A (alkali metals) has the largest atomic radius among the groups in the periodic table.

Front

What happens to atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases as you move down a group because additional electron shells (energy levels) are added.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

Which group 4A element has the highest ionization energy?

Back

Carbon has the highest ionization energy among the group 4A elements.

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 in period 4 has the highest electronegativity?

Back

Bromine has the highest electronegativity in period 4.

Front

How does atomic radius change across a period from left to right?

Back

Atomic radius decreases across a period from left to right due to increasing nuclear charge, which pulls electrons closer to the nucleus.

Front

What is the trend of ionization energy across a period?

Back

Ionization energy generally increases across a period from left to right.

Front

What is the trend of electronegativity across a period?

Back

Electronegativity generally increases across a period from left to right.
