ionic substances

.. "2 or more atomics ionically bonded in a crystal lattice structure"

.. https://en.wikipedia.org/wiki/File:Potassium-bromi...

.. notei ionic substances are not molecular!

compounds

.. molecules containing atoms of 2 or more different elements

.. ionic substances.(ionic substances are always compounds)

examples

.. CH4 - molecular compound

.. H2.. - molecular substance (NOT a compound)

.. CO2 - molecular compound

.. O3.. - molecular substance that is NOT a compound

.. NaCl - ionic compound

.. KBr - ionic compound

Answer 2

A compound is created when atoms of two different elements combine.

    Oxygen (O2) is only a molecule because it is two oxygen atoms bonded.

    CO2 is a compound because it is two different elements bonded.

    Nitrogen (N2) is a molecule.

    Water (H2O) is a compound.

    Ozone (O3) is a molecule.

    Sugar (C12H22O11) is a compound.

Answer 3

A compound consists of at least 2 different elements.

A molecule can consist of a single element.

Answer 4

The same as the difference between a link and a chain.
