Compare the gravitational and electrical forcews between proton-proton, proton-electron, electron-electron.

Compare the properties of electron, proton and neutron

The dimensions of an atom are of the order of an angstrom. Thus there must be large electric fields between the protons and electrons. Why, then is the electrostatic field inside a conductor zero?

Give the ratio of magnitude of the electrostatic force to the gravitational force between a proton and an electron.

Calculate the magnitude of the electrostatic force exerted by the proton on the electron in the hydrogen atom and compare it with the weight of the electron. Given that mass of electron is 9.1 xx 10^-31 kg, charge on electron is 1.6 xx 10^-19 C and radius of hydrogen atom is 0.53 overset(@)A .

Calculate the number of electron, proton and neutron in carbonate ion .

In an electric field an electron is kept freely. If a proton replaces this electron, what will be the relationship between the forces experienced by them?

Find the number of proton & electron in Al3+ ion ?

State three ways by which a proton differs from an electron.
