Particles in a gas have more energy than particles in a liquid. Because in gaseous state particles are free to move around due to which kinetic energy of molecule or gas increases and hence overall energy increases
£ is not a molecule. It is a currency. That is pounds sterling, used in the U.K.
Answer:
The nucleus of atom is composed of two subatomic particles that each have charges.
- Protons, which are positively charged particles.
- Neutrons, which are neutrally charged particles.
Both reside in the nucleus of an atom. The amount of protons and neutrons (Electrons can to) is what helps us identify each atom apart. Electrons are NOT in the nucleus of atom but orbit it in outer layers called orbitals.
