Concept explainers
Interpretation:
The reason due to which one cannot pass hand through a solid object made up of atom needs to be explained.
Concept introduction:
Atom is the unit of the matter. It composed of protons, electrons, and neutrons. The central region of an atom is the nucleus, the protons, and neutrons present in the nucleus of the atom. The Outer sphere-like structure is a shell where the electrons are moving around the nucleus.
Answer to Problem 112A
The atoms having electron clouds around the nucleus make it just like a solid object, due to the presence of electron cloud one cannot pass hand or any object through it.
Explanation of Solution
The atom consist three main subatomic particles. The revolving of an electron is due to the
In nature, the intermolecular forces are very strong in the solid particle and the intermolecular space is negligible so the particles are tightly joined together. In the solid-state, the arrangement of particles very close to each other, and two atoms are joined in a fixed and complex manner, there is no space to pass any object through it for example your hand or any other object.
The electrons are repelled to each other and the nucleus attracted them with equal force of attraction. So a cloudy wall is created due to center force of attraction and one cannot pass hand through it.
