Its atomic structure.
For chemical properties it is the configuration of valence electrons (1 .. 8).
For physical properties it includes the structure of the nucleus and all electron orbitals.

Which subatomic particle idetifies an atom as that of a particular element?
The number of protons defines the element.
What uniquely defines a chemical element?
Atomic number
Can a single element have more than one atomic number?
No. Atomic number defines the element.
Does the number of electrons an atom has defines what kind of element it is?
yes
Are two atoms that have the same number of protons the same element?
Yes. The number of protons defines the element.
What element is more likely to be found in an organic compound?
Carbon - the element that defines the chemical word "organic".
What atom or isotope of an element has an atomic mass of 26 charge of 3 13 protons 13 neutrons and 10 electrons?
The number of protons identifies this element as aluminum, which has an atomic number of 13. The number of protons is an element's atomic number on the periodic table. Every element has its own unique atomic number which defines it as that element.
What number on the periodic table defines the element and does not change?
Atomic number
Why are there not isotopes with unusual numbers of protons?
If the number of protons changes so does the element, as the number of protons defines the element.
What aspect of an atom's subatomic particles defines which element it is?
The number of protons determines the element, and is the same as its atomic number.
How do you know if the equation defines a function?
Suppose the function, y = f(x) maps elements from the domain X to the range Y. Thenfor every element x, in X, there must be some element y in Y, andfor an element y, in Y, there can be at most one x in X.
What configuration defines an isotope of the same element?
Isotopes of one particular element differ only in their number of neutrons in nucleus.
