Question

Write down the modification of the following Dalton’s atomic theories.
(i) Atoms can neither be created nor destroyed
(ii) Matter is made up of smallest, indivisible practices called atoms

Answer 1

Postulates of Dalton’s Atomic Theory

• The matter is made up of indivisible particles known as atoms.

• The properties of all the atoms of a given element are the same including mass. This can also be stated as all the atoms of an element have identical mass while the atoms of different elements have different masses.

• Atoms of different elements combine in fixed ratios to form compounds.

• Atoms are neither created nor destroyed. This implies that during chemical reactions, no atoms are created nor destroyed.

• The formation of new products (compounds) results from the rearrangement of existing atoms (reactants).

• Atoms of an element are identical in mass, size and many other chemical or physical properties, but atoms of two-different elements differ in mass, size, and many other chemical or physical properties.

Answer 2

Explanation:

hey mate

the first one is true

but the second one has some modification

the atom is still have tinier particles known as proton neutron and electron
