Atomic number
Yes.
Every element has a specific number of protons, which is how an element is identified. That gives its atomic number. The number of neutrons can vary, and therefore is not useful in identifying an element.
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
the number of neutrons.
Pretty sure it's the valence electrons
The number of valence electrons. :) have a good day breh
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
A large geographical area, such as a state
One characteristic property of an element is the number of electrons it has.
The atomic number of an element is unique to that element. The atomic number is equal to the amount of electrons in one atom of that element. As each element categorically has it's own amount of electrons, you can identify an element from this number.
"Multiplicative Identify Property of One" or "Identity Property of Multiplication"
The atomic number is an identifier for each chemical element.
The Atomic number
The number of protons the element has
Atomic number
The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.
