Which of the following is a characteristic of science?

it asks questions about the natural world.
it asks questions that cannot be tested.
it is done by only one scientist at a time.
it uses opinions to make conclusions.
10

The correct answer will be option-It asks questions about the natural world.

Explanation:

Science is a branch of study related to the natural world based on the scientific methods evolved which includes the observation of the natural events and then experimentation to know the answer.

The approach of science is to gain the truths in the form of general laws and theories about the physical world. The scientific knowledge can be gained only through the scientific method which initiates with making an observation and asking a scientific question which can be answered.

Since the approach involves understanding the scientific phenomenon which can be done by asking the scientific question through scientific method thus, the selected option is the correct answer.

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.
