Which sphere is not directly studied in one of the main branches of Earth space science geology astronomy meteorology or oceanography A biosphere B exosphere C atmosphere D hydrosphere. These are the main differences between molecules and compounds. There are over 100 different elements , which are made. Because the bond formed between sodium (Na) and the chlorine (Cl) atom is ionic in nature, it is formed due to the transfer of electrons from Na to Cl, which results in the formation of ions (Na + and Cl - ), later these ions are attracted by the electrostatic force of attraction and form the ionic bond in NaCl.

Optical Properties: Perfect sodium chloride crystals transmit about 90% of light between 200 nanometers and 20 micrometers. It normally has an oxidation state of +1, and its single valence electron is lost with great ease, yielding the colourless sodium cation (Na +). Count the number of electron groups and identify them as bond pairs of electron groups or lone pairs of electrons. However, table salt actually isn't pure sodium chloride.
