The correct option is"Various scientists found that atoms of a particular element have unique properties".

Explanation:

Postulates of Dalton's Atomic theory were:

Matter is made smallest and indivisible unit known as atom.All the atoms of same element has same mass and size. Where as atoms of two different element will differ in mass and size.Atoms of different element combine in fixed proportion to form a compound.In a chemical reaction, rearrangement of the atoms takes place.Atoms of an element same in size and mass have same chemical and physical properties.

From the enlisted options the correct option which explains one of the postulates written above is "Various scientists found that atoms of a particular element have unique properties".

Answer from: Quest

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

Answer from: Quest

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"
