B
Atoms are indivisible particles, which cannot be created or destroyed
in a chemical reaction,

compound​

Answer 1

$\mathtt{\huge{\bf{\underline{\pink{Answer:- }}}}}$

Option B.) Atoms are indivisible particles, which cannot be created or destroyed in a chemical reaction.

The Dalton's atomic theory states that :-

• Elements consist of minute, indivisible, indestructible particles called atoms.

• Atoms of an element are identical to each other.

• They have the same mass and size.

• Atoms of different elements differ in properties and have different masses and sizes.

• Compounds are formed when atoms of different elements combine with each other in simple numerical ratios such as one-to-one, one-to-two, two-to-three and so on.

• Atoms cannot be created, destroyed or transformed into atoms of other elements.

• The relative number and kind of atoms are always the same in a given compound.
