Answer: The movement of heat from a warmer object to a cooler one is called heat transfer
Explanation:
Answer:
If a neutral atom has 22 protons inside its nucleus, it will have 22 electrons orbiting the nucleus.
Explanation:
An atom is the smallest amount of matter that undergoes chemical changes and is made up mainly of subatomic particles: electrons, protons and neutrons. The atomic nucleus is made up of protons, with a positive electric charge, and neutrons, which have no charge, while electrons, with a negative electric charge, revolve around the nucleus.
A neutral atom is one that lacks an electrical charge due to a trade-off between the number of its protons and electrons. In other words, although it has an electric charge, it is balanced between protons, electrons and neutrons. So in a neutral atom, the number of electrons equals the number of protons because the negative charge of the electrons is offset by the positive charge of the protons.

What happens in the artificial transmutation is that the nucleous is bombarded with high energy particles which we can describe as kinetic energy and the idea for them is to induce what we call transmutation. Also what happens is that the high energy particles are accelerated. One of the examples is when nitrogen is transformed into hydrogen by combining its nucleous with an alpha particle
Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were indivisible particles, and Thomson's discovery of the electron proved the existence of subatomic particles.
