Convert 238 cm to the unit km. 0.00238 km 0.238 km 2.38 x 105 km 2.38 x 107 km

238 cm = 0.002 38 km

Step 1. Convert centimetres to metres

238 cm × (1 m/100 cm) = 2.38 m

Step 2. Convert metres to kilometres

2.38 m × (1 km/1000 m) = 0.002 38 m

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.

i'm assuming that the correct answer is indeed the first one/ "a"..
