Dalton. Dalton's atomic theory stated that atoms are indivisible and indestructible and unchangeable.
The statement that atoms of the same element are exactly alike is attributed to John Dalton, who proposed the atomic theory in the early 19th century. Dalton's theory posited that all atoms of a given element are identical in mass and properties, which laid the foundation for modern chemistry. However, it is important to note that later discoveries, such as isotopes, revealed that atoms of the same element can differ in mass due to variations in the number of neutrons.
Element
It is an injective relation.
An atom with 17 protons is chlorine. (It is unnecessary to say "exactly" because the number of protons can only be whole numbers.)
John Dalton postulated that atoms of the same element are exactly alike in his atomic theory developed in the early 19th century.

He Proposed To Her In Hawaii But I Dont Know When Exactly.
yes they do
It is an invertible function.
it is a function to where every element in the range equals exactly one element in the range, or for every x there is exactly one f(x)
