What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons. It generally increases down a group and decreases across a period in the periodic table.

Front

Which element has the largest atomic radius in the given options: Sodium (Na), Magnesium (Mg), Aluminum (Al), Chlorine (Cl)?

Back

Sodium (Na) has the largest atomic radius among the given options.

Front

How does temperature affect the solubility of solids in liquids?

Back

As temperature increases, the solubility of most solids in liquids increases.

Front

What does the subscript '2' in Ca(NO3)2 indicate?

Back

It indicates that there are two nitrate ions (NO3-) needed to balance the charge of one calcium ion (Ca2+).

Front

Which element is the least electronegative among Fluorine (F), Lithium (Li), Oxygen (O), and Nitrogen (N)?

Back

Lithium (Li) is the least electronegative element among the given options.

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 trend of atomic radius in the periodic table?

Back

Atomic radius increases down a group and decreases across a period from left to right.

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 is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.
