The number of protons, which is the atomic number of an element, determines the identity of an element.
The number of protons in the nucleus determines the identity of an atom.
An element is defined by the number of protons in the atomic nucleus of its atoms.
The number of electrons can vary in ions. The number of neutrons can be different in the possible isotopes of an element, which are nonetheless the same element.
The proton. The atomic number, or the identity of the atom, is based on the number of protons. While the number of neutrons and electrons may vary, they only have an effect on the atom's mass or charge. But an atom with 2 protons will always be Helium, and an atom with 35 protons will always be Bromine.
The number of protons in the nucleus of each atom determines the idenity of an element.
They are atoms
This particle is the proton.
This particle is the proton.
This particle is the proton.
What
protons
no i cant answer it
Assuming that you mean the chemical properties, the electrons are what define each element. If you meant subatomic particles, then it doesn't matter; each subatomic particle has unique characteristics.
proton you can change the number of neutrons and electrons and still have the same element
Every subatomic particle has mass, so every particle will cause a slight mass change. However, in an isotope, the mass change between the parent and daughter is caused by a change in the number of neutrons.
This particle is the proton.
The identity of a chemical element is given by the number protons.
The number of protons determines what is the element.
protons
There is no individual sub-atomic particle that is responsible for the identity of an element. It is the way the electrons, protons and (neutrons) are arranged in an element that gives it it's identity.
The number of protons is determining the element
In the chemical reactivity of atoms electrons are involved.
The number of protons in an atom determines which element it is (i.e Silver-47 protons vs. Gold-79 protons)
An "element" is not a subatomic particle. Your question makes no sense and is therefore unanswerable.Another answer:Since an element is not a subatomic particle, the only answer can be a proton.
The number of protons tells you which chemical element the atom is. The number of neutrons determines the isotope of the element.
The number of protons defines the element.
Neutron
