What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, usually between non-metal atoms.

Front

Which type of compound generally has a high melting point?

Back

Ionic compounds generally have high melting points due to the strong electrostatic forces between the ions.

Front

Which type of compound typically has low melting points?

Back

Covalent compounds typically have low melting points because the forces between the molecules are weaker.

Front

What is the electrical conductivity of ionic compounds in solid state?

Back

Ionic compounds do not conduct electricity in solid state because the ions are fixed in place and cannot move.

Front

What is the electrical conductivity of ionic compounds in molten or dissolved state?

Back

Ionic compounds conduct electricity when molten or dissolved in water because the ions are free to move.

Front

What is the solubility of ionic compounds in water?

Back

Many ionic compounds are soluble in water due to the interaction between water molecules and the ions.

Front

What is the solubility of covalent compounds in water?

Back

Many covalent compounds are not soluble in water, especially those that are non-polar.
