The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
The nucleus of an atom CANNOT itself contain atoms.
Atoms can be changed through chemical reactions or nuclear processes, such as fusion or fission. However, the total number of protons, neutrons, and electrons remains the same before and after the change, due to the law of conservation of mass.
No, an atom cannot gain or lose protons. Protons are the positively charged particles within the nucleus of an atom, and changing the number of protons would change the atom's identity. However, atoms can gain or lose electrons, which affects their charge but not their identity.
A compound can contain a single atom of gold, but a single atom of gold alone, by itself, cannot be a compound.
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
atoms cannot be divided
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.
Sometimes, an atom cannot be split.
I cannot answer this question.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
Atom
An atoms protons cannot change.The number of neutrons can change (gain or lose) to form an isotope (ex. Hydrogen naturally has no neutrons. But it can gain neutrons to form Heavy Hydrogen, or in other words, a Hydrogen Isotope).An atom can gain or lose electrons to form an ion. Usually an atom will gain or lose electrons to fill its valence (outermost) shell. It takes just as much energy to gain an electron as it is to lose one, so an atom will always look to lose or gain the least amount of electrons possible. (ex. Oxygen has 6 valence electrons. It will look to gain 2 electrons, rather than lose 6).Protons: DO NOT CHANGENeutrons: Can change to form an isotopeElectrons: Can change to form an ion
An atom is the smallest unit of matter that cannot be broken down into smaller particles without losing its unique properties. Each atom consists of a nucleus composed of protons and neutrons, surrounded by electrons in orbitals.
Atom
Nuclear change is the change in the nucleus of the atom.
