The type of bonding in sodium chloride is ionic. This sodium atom loses its outer most electron to complete its outer most shell to form a sodium ion (positive) and donates it to the chlorine atom which a...

Point 1: Stability constant with CO is greater than with 02.Point 2: Bond with CO is stronger than with 02.Explanation: In haemoglobin a central Fe2+ ion in an octahedral complex compromising four dative ...

The relative atomic mass (A_r ) is calculated from 2 things : mass numbers of its isotopes and abundance of these isotopes.Let's use Chlorine as an example. Chlorine naturally exists as two isot...

All atoms are neutral because all atoms have the same number of protons as they have electrons. Atoms are made up of a nucleus and electrons that surround their nucleus in shells. The nucleus contains pro...
