The Number of protons of an atom defines which element it is, for example an atom with three protons will always be Lithium
If it is an atom, not an ion, then the number of protons = no. of electrons
differing numbers of neutrons effect the Atomic Mass of an atom, differing atomic masses create isotopes, but they are still the same element?
what sets an atom of one element from atoms of all other elements
is the elements atomic number,

RafaA lot of things.... Some examples: electronegativity, charge, radius/size, electron affinity, ionization energy, Zeff (Effective Nuclear Charge), reactivity (related to some things listed before), etc.
For an easy course (which I'm assuming you're in), you probably only need to know the first three.

What information will an elements atomic number give you?
Atomic no. helps to know 1. the position of element in the periodic table2. Common properties3. Electronic Configuration4. Common electrovalencies and oxidation states.5. Many other properties.
What is the smallest amount of an element?
The smallest amount of an element is one atom. Atoms are the basic unit of an element and cannot be divided further without losing the element's properties.
What does it mean if an atom has no subscript in a chemical formula?
There is one atom of that element in the molecule.
Is one move of zinc the same as one atom of zinc?
No, one move of zinc is not the same as one atom of zinc. A move of zinc typically refers to transferring a set amount of the element from one location to another, while an atom of zinc specifically refers to one individual unit of the element zinc.
If a substance is composed entirely of one type of atom it is known as a?
It is known as an element. An element is a substance that is made up of only one type of atom, characterized by a unique atomic number on the periodic table.
