The s,p,d,f configuration for cobalt (Co) is 1s22s22p63s23p64s23d7, determined by the position of the element on the periodic table. The electron configuration for Cobalt at ground state would simply be Co: [Ar] 4s²3d⁷.

The electron configuration of Cobalt will end in d block as Cobalt is an inner transition metal. Cobalt is in the 7th column of the d block and therefore has 7 d electrons d7.

Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry.A Fischer projection always uses an eclipsed conformation. A Newman diagram can represent either an eclipsed conformation or a staggered conformation or a skew conformation.

Atomic  number  is  the  fundamental properties  of  an  element.  Every atom  is  identified  by  its  unique atomic  number.  Atomic  number  is equal  to  the  number  of  protons present in an atom of the element.

‘Suppose’ and ‘if’ both are used to guess, or think, or imagine something and both means the same thing. So, using them together is superfluous. So, ‘if’will be used.
