Question

if atoms are created when man-made elements are made then how does that justify Dalton's 3rd postulate that states atoms can neither be created nor destroyed in a chemical reaction??

Answer 1

For preparing a man mad element, its atom is synthesized by using the atom of natural or existing elements.

Either a larger atom is broken down to produce a new small atom or fell small atoms are fused together to produce a

new larger atom. These fission and fusion reaction are balanced and follow the low of conservation of mass and Dalton atomic theory.
