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.
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.
The number of protons in the nucleus of the atom is what determines its identity. Oxygen atoms have 8 protons, while carbon atoms have 6 protons. This unique number of protons gives each element its specific atomic number and identity.
Electrons can influence an atom's chemical behavior by participating in reactions or forming bonds with other atoms. However, electrons alone cannot change the fundamental identity of an atom, as that is determined by the number of protons in the nucleus.
The molecular formula provides information about the number and type of atoms in a molecule. This formula gives the actual number of each type of atom in a molecule but does not provide information on the arrangement or connectivity of the atoms within the molecule.
The number of protons in the nucleus of the atom determine its identity.
By the number of protons it has.
This is a chemical reaction.
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.
All stable Atoms have the same neutral charge, and cannot be divided into smaller units while retaining their chemical identity
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.
In a sample of pure copper, all atoms have the same number of protons, which determines the element's identity.
All is true; theory of Leukippus and Democritus was 2 500 yers ago only a theretical (but correct) supposition.
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 atoms of any single element have the same number of protons and electrons.
