When scientists first studied electromagnetic energy, many theories were proposed to explain how these waves travel through space. Which statement below best describes how scientists arrived at the current understanding of electromagnetic energy? Scientists all agreed with a single researcher who proposed the current theory.

Scientists completed internet searches of all available data to arrive at the current theory.

Scientists debated the theories with each other and compared the theories with scientific observations.

Scientists were able to observe the light from the brightest star in space, which verified the current theory

Explanation:

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.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
