What is the trend of atomic radius down a group in the periodic table?

Back

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

Front

Define 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 has the highest electronegativity in the periodic table.

Front

What is the relationship between ionization energy and electronegativity?

Back

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

Front

What is the trend of atomic radius across a period in the periodic table?

Back

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

Front

What is the significance of valence electrons in determining chemical properties?

Back

Valence electrons determine an element's reactivity and bonding behavior.

Front

How does the ionization energy change from Li to Cs?

Back

Ionization energy decreases from Li to Cs due to increased atomic size and shielding effect.

Front

What is the general trend of reactivity for alkali metals?

Back

Reactivity increases down the group for alkali metals.

Front

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

Back

Electronegativity decreases down a group due to increased distance between the nucleus and bonding electrons.
