Question

Atoms of an element are all identical to
each other and different from the atoms of
other elements​

Answer 1

All atoms of a given element are identical in mass and properties. Dalton proposed that every single atom of an element, such as gold, is the same as every other atom of that element. He also noted that the atoms of one element differ from the atoms of all other elements.

Answer 2

Hii I will help you ✌️

=> No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical. ... The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element.
