Match the items in column I with items in column II and select the correct option.

Matrix:

	Column I		Column II
a)	Proust	i)	John Dalton
b)	Hydrogen	ii)	Law of conservation of mass
c)	12u	iii)	Law of constant proportions
d)	Lavoisier	iv)	Smallest atom
e)	Ferrum	v)	Carbon-12
f)	Indivisible atom	vi)	Latin name

Joseph Proust gave the law of constant proportions. The law of constant proportion states that a given chemical compound always contains its component elements in a fixed ratio and does not depend on its surface and method of preparation. The smallest atom is the hydrogen atom. 

The element hydrogen has the smallest atomic mass which has a proton and an electron. The atomic mass of carbon-12 is 12u. The law of conservation of mass was given by Lavoisier. 

It states that mass can neither be created nor destroyed in chemical reactions. The Latin name of iron is Ferrum with the symbol Fe. John Dalton’s theory said that an atom was an indivisible particle. 

Hence, the correct match is =>  a – iii; b – iv; c – v; d – ii; e – vi; f – i
