The number of protons in the nucleus of the atom determine its identity.
The energy involved in chemical reactions is not so strong to affect the identity of atoms; only nuclear reactions can modify an atom.
yes
If by its identity you mean its atomic number, no. Neutrons only count towards the Atomic Mass Number, or AMU.
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.
All is true; theory of Leukippus and Democritus was 2 500 yers ago only a theretical (but correct) supposition.
By the number of protons it has.
This is a chemical reaction.

All stable Atoms have the same neutral charge, and cannot be divided into smaller units while retaining their chemical identity
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
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.

All atoms of any single element have the same number of protons and electrons.
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.
