The number of protons in the nucleus of the atom determine its identity.
What else can I help you with?
Why doesn't an atoms identity change during a chemical change?
The energy involved in chemical reactions is not so strong to affect the identity of atoms; only nuclear reactions can modify an atom.
Do atoms or molecules change identity when a change of state occurs?
yes
Do you count neutrons to find an atoms identity?
If by its identity you mean its atomic number, no. Neutrons only count towards the Atomic Mass Number, or AMU.
How can you tell two atoms apart?
Atoms can be distinguished by the number of protons in their nucleus, known as the atomic number. Atoms of different elements have a unique number of protons, which determines their identity on the periodic table. Additionally, atoms can also be differentiated by their electron configuration and isotopic composition.
Was not among Democritus and ideas Matter consists of tiny particles called atoms. Atoms retain their identity in a chemical reaction. Atoms are indestructible. Atoms are indivisible.?
All is true; theory of Leukippus and Democritus was 2 500 yers ago only a theretical (but correct) supposition.
How can you determine an atoms identity?
By the number of protons it has.
What changes the identity of matter by rearranging the atoms?
This is a chemical reaction.

What has all atoms the same?
All stable Atoms have the same neutral charge, and cannot be divided into smaller units while retaining their chemical identity
In a sample of pure copper all atoms have the same what?
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
When the substance undergoes a chemical change its identity deos not change?
That's correct. In a chemical change, new substances are formed through rearrangement of atoms, but the identities of the original atoms remain the same. This is because atoms are not created or destroyed during chemical reactions, they simply rearrange into new combinations.

What do all atoms of any single element have in common?
All atoms of any single element have the same number of protons and electrons.
What determent's an atoms identity?
An atom's identity is determined by the number of protons in its nucleus, which is called its atomic number. This number determines the element to which the atom belongs. Electrons can be gained or lost to form ions, but as long as the number of protons remains the same, the atom's identity remains unchanged.
