An odor released across the room eventually reaches your nose because a. the gas particles travel directly to your nose from the source. b. the gas particles spread out and fill the space of the room, including your nose. c. the heavy weight of the gas particles them travel and stick to receptors inside your nose. d. the gas particles get carried along invisible clouds of water vapor to your nose.

the formula would be mgso4

mgso[subscript]4

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.
