Question

Which of the following statements is part of Dalton's Atomic Theory?

a. elements in the same column have similar properties
b. elements are defined by the number of protons present
c. atoms from the same element are similar
d. atoms are mostly empty space
e. none of the above

Answer 1

All atoms of a given element are identical.

The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights.

Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms.

Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.

OK all these above are true statements of the theory. I hope this helps
