Yes.
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
- the electron configuration is the same- the number of valence electrons is the same
it is called a complex
Chemical reactions are changed by ionization. Ionized atoms act chemically differently than unionized atoms.
Dalton said that all atoms of one element are identical. they are chemically identical but not identical in mass. he did not know of isotopes, which are chemically identical atoms with different numbers of neutral neutrons. ex: all carbon atoms act the same chemically but some mass at 12, others at 14.

Seselective service act
I dont know
the hydrogens atoms act as if they are positively charged.

The atoms in iron are little groups that act like tiny magnets also found in nickel and cobalt!
molecule
Everying in the universe is made up of atoms. If atoms didnt agsist, then life would act as if you were never born.
Polyatomic atoms
