8 G is a colourless crystalline solid which reacts with dilute nitric acid to give a colourless solution, H, and a colourless,
odourless gas, I, ewhich turns lime water milky. G has a lilac

a) identify G, H and I. b) write an equation (full or ionic) for the reaction between G and dilute nitric acid

wher is the rest of the question

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
