One way in which elements differ from each other is the structure of the electron cloud in each elements atoms in electron cloud an electron that is farther away from the nucleus has

The question is incomplete, the complete question is:

One way in which elements differ from each other is the structure of the electron cloud in each element’s atoms. In an electron cloud, an electron that is farther away from the nucleus has

a greater charge than an electron near the nucleus.

a smaller charge than an electron near the nucleus

a higher energy than an electron near the nucleus.

a lower energy than an electron near the nucleus.

a higher energy than an electron near the nucleus.

Explanation:

Energy levels increase outwards from the nucleus. An electron that is nearest to the nucleus is said to be in its ground state, this is the lowest energy state of that electron. As we move outwards from the nucleus, the energy levels increase progressively. Hence, the farther electrons are from the nucleus, the greater their energy level and the greater the energy of the individual electrons.

it should be p1 v1 = p2 v2

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
