Its protons. The atom changes depending on how many protons it has. See also atomic number.
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
It is the same for each and every element, it's the number of protons in the nucleus of one atom of the element.

An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
the number of electrons can be different; it makes the element become an ion.
An element is a class of substances An atom is the smallest possible piece of an element. An isotope is an electrically charged atom.
Every atom of one element has different no. of electrons than any atom of any other element.
The atomic number or z number or the number of protons is what makes one atom different from another. The atomic number or z number or the number of protons is what makes one atom different from another.
It has a different amount of protons, nuetrons and electrons than any other element's atom.

The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
