All atoms of any single element have the same number of protons and electrons.
All atoms are elements. Single (or even a "few") atoms do not have the properties of large masses of atoms.
Number of protons in the nuclei of their atoms.
Not necessarily, because most elements have isotopes, which have slightly different weights. However, atoms of a particular element always have the same number of protons, equal to the atomic number of the element.

Argon is an element and all the atoms in argon are argon atoms.
All atoms are elements. Single (or even a "few") atoms do not have the properties of large masses of atoms.
Number of protons in the nuclei of their atoms.
No, the isotopes of a single element differ in the no. of neutrons
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.
He concluded that all atoms of an element have same mass and identical chemical and physical properties.
No, the isotopes of a single element differ in the no. of neutrons
According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
Not necessarily, because most elements have isotopes, which have slightly different weights. However, atoms of a particular element always have the same number of protons, equal to the atomic number of the element.
All the atoms have the same number of protons (element type).
Atoms of all isotopes of a single element have the same number of protons in their nuclei but have different numbers of neutrons if they have different mass numbers.

The number of protons is identical in all atoms of an element.
