The reason why it is said that an atom is mostly composed of empty space.
Answer to Problem 1RQ
An atom is composed with nucleus and electrons in a surrounding cloud. Thus inside of an atom is empty
Explanation of Solution
An atom is made up of electron proton and neutron. The proton and neutron together formed the nucleus of the atom. And the electron is in a surrounding cloud.
As an example, considering the simplest type atom hydrogen which is having one proton and one electron. The proton is having diameter of about
The volume of nucleus is in the range of

- It may be argued on theoretical grounds that the radius of the hydrogen atom should depend only on the fundamental constants h, e, the electrostatic force constant k = 1/4πℰ0, and m (the electron’s mass). Use dimensional analysis to show that the combination of these factors that yields a result with dimensions of length is h2kme2.arrow_forwardWhy do you think that the energy level in the n- region is lower than the p-region?arrow_forwardIt is relatively easy to strip the outer elections from a heavy atom like that of uranium (which then becomes a uranium ion), but it is very difficult to remove the inner electrons. Why do you suppose this is so?arrow_forward
- The atoms that constitute your body are mostly empty space, and structures such as the chair you’re sitting on are composed of atoms that are also mostly empty space. So why don’t you fall through the chair?arrow_forwardThe nucleus of a certain atom has a radius of 4.0 × 10^-15 m. An electron orbits the nucleus at a radius of 1.5 × 10^-10 m.
