PERIODICITY

Front

What is periodicity in chemistry?

Back

Periodicity refers to the recurring trends that are observed in the properties of elements as you move across or down the periodic table.

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 has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity of all elements.

Front

What is ionization energy?

Back

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

Front

How does atomic radius change across a period?

Back

Atomic radius decreases across a period from left to right due to increasing 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 electronegativity in the periodic table?

Back

Electronegativity increases across a period and decreases down a group.

Front

What is the relationship between ionization energy and electronegativity?

Back

Generally, elements with high ionization energy also have high electronegativity.

Front

Which element has the largest atomic radius among potassium, rubidium, francium, and cesium?

Back

Francium has the largest atomic radius.

Front
