What is ionization energy?

Back

The energy required to remove an electron from an atom or ion.

Front

Which element has the largest atomic radius?

Back

Cesium (Cs) has the largest atomic radius among all elements.

Front

How does atomic radius change across a period?

Back

Atomic radius decreases from left to right across a period due to increased nuclear charge.

Front

How does atomic radius change down a group?

Back

Atomic radius increases down a group due to the addition of electron shells.

Front

What is the trend of ionization energy across a period?

Back

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