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.

What identifies the type of element in an atom?

It's the other way around. The atomic number identifies the type of atom in an element. All of the atoms of an element have the same atomic number, which is the number of protons in an atom of an element. Each element has a unique atomic number.


What is an atomic number and where can you find one listed?

the atomic number is the number of protons of an element. The atomic number specifically identifies an element. You can find it on the Periodic Table of Elements.


Explain how the atomic number of an element identifies the element?

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.

What does a atomic number determine?

The atomic number determines the element. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number, which identifies it as that element.


Atomic number vs mass number?

Atomic number is the number of protons in a nuclide. This identifies the element. Mass number is the number of nucleons in a nuclide, a nucleon being a proton or a neutron. This, together with the atomic number, identifies which isotope of the element it is.


Which subatomic particle identifies an atom as that of particular element?

The number of protons defines the element.

Atomic number is the number of an atoms?

No. Atomic number is the number of protons in the nucleus of an atom. Each element has a unique atomic number that identifies it as that element.


Which subatomic particle identifies the element?

You can define an element by the number of its protons and neutrons and its electron configuration.


What number uniquely identifies an element?

This is the atomic number (equal to number of protons).


How atomic number of an element identifies the element?

Each element has an unique atomic number in the periodic (Mendeleev) table of elements. The atomic number is the same as the number of protons and electrons.
