What will be the formula of '$M$' nitrate based on the given Lothar Meyer curve?

Match the following and select the correct option.

List-$I$	List-$II$
$(1)$ Lothar Meyer	$(A)$ First to present a periodic table showing correct arrangement up to Calcium.
$(2)$ $A$.$E$.$B$. de Chancourtois	$(B)$ Arranged elements in horizontal and vertical rows based on atomic weight.
$(3)$ Newlands	$(C)$ Discovered the element with atomic number $101$.
$(4)$ Seaborg	$(D)$ Suggested that arrangement based on atomic weight is an important concept in the periodic table.
	$(E)$ Presented the first possible periodic table.
	$(F)$ Arranged elements into groups of three.
	$(G)$ Law of Octaves.

Explain the contribution of Newlands to the periodic table.

State whether the following statements are true or false:
$(i)$ The chart of elements presented by $Courtois$ could predict the stoichiometry of oxides of some metals.
$(ii)$ $Li, Na, Rb$ are known as $Döbereiner's$ triads.
$(iii)$ In $1863$,$Newlands$ classified the $56$ discovered elements into $18$ groups.
$(iv)$ $Mendeleev's$ periodic table is based on the atomic number of elements.

On the basis of which important property did Mendeleev classify the elements in his periodic table? Was he able to stick to it firmly? Explain.
