Explanation:
An atom is made up of three fundamental particles:
- Protons are positively charged particles in an atom
- Electrons are negatively charged.
- Neutrons carry no charges.
In a neutral atom, the number of protons and electrons are the same and equal.
Most atoms are usually depicted this way:
ᵃₙX
where a is the mass number of the atom.
n is the atomic number
X is the symbol of the atom
The mass number is the sum of the number of protons and neutrons
Atomic number is the number of protons.
In a neutral atom, the atomic number is also the number of electrons since the atom is neutral. It has not gained or lost any additional electrons.

Answer: Larmor suggested in 1919 that a self-exciting dynamo could explain the magnetic field of the earth, as well as that of the sun and other stars, but it was Elsasser and Bullard in the 1940s who showed how motion in the liquid core of the earth might produce a self-sustaining magnetic field. By this time seismology and other studies had given a clearer picture of the earth, as having a solid inner core, a liquid outer core, both with a composition more of metal (mainly iron) than rock, and a rocky mantle, all below a thin crust that is all we can directly see. Energy from radioactivity travels outwards as heat, producing thermal convection in the core. It seems that this convection is the cause of the earth's magnetic field, although our knowledge of the core and its dynamics is sketchy. Our knowledge is limited to saying that flow regimes like those that may be occurring in the core can produce self-sustaining dynamos, with characteristics similar to that needed to produce the earth’s magnetic field.
