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.

What is the formula for sulfur tetrafluoride?

Back

SF4.

Front

What is the difference between ionic and covalent compounds in terms of melting points?

Back

Ionic compounds generally have higher melting points than covalent compounds due to the strong electrostatic forces between ions.

Front

What is an ion?

Back

An ion is an atom or group of atoms that has an electric charge due to the loss or gain of one or more electrons.

What is the formula for trinitrogen monochloride?

Back

N3Cl.

Front

How do you determine if a compound is ionic or covalent?

Back

Check the elements involved: if it consists of metals and non-metals, it is likely ionic; if it consists of non-metals only, it is likely covalent.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons; a large difference in electronegativity between two atoms typically leads to ionic bonding.
