electrons revolve around the nucleus . shell is the path of the electron whre the electrons revolves. subshell is the region around the nucleus where you can find the probability of electron most. so shell attains circular/elliptical shape where as subshell attains different shapes(spherical,dumb-bell...etc)

Can you mix two type of transformer oil like shell diala B and nytro 10XN and how or what percentages?
One can mix shell Dial Oil B and nytro 10xn at 2 parts shell Diala and one part nytro 10xn. The advantages would be good pouring flow even at low temperature Both oils are napthenic.
What is critical flow and sub critical flow of fluids?
Critical flow is the special case where the froude number (dimensionless) is equal to 1. i.e. The velocity divided by the square root of (gravitational constant multiplied by the depth) =1. Sub critical flow i has a froude number less than 1, and is therefore characterised by slow moving deep water. Supercritical flow is defined as having a froude number greater than 1 and is therefore characterised by shallow fast moving flows.

How can you tell the doffermce between 2s subshell and 2p subshell?
You can tell the difference between a 2s sub-shell and 2p sub-shell from their energy levels, because a 2p sub-shell is a higher energy level than a 2s sub-shell.
What is shell and sub shell?
they are both the same meaning

What number of electrons that can be held in first orbit closest to the nucleus?
The orbit or electron shell closest to the nucleus is the 1s sub-shell. It can hold 2 electrons before the 2s sub-shell is filled. H and He have their electrons in this shell (the 1s)

Why is 2d1 not possible?
A break down of 2d1:2 = the quantum energy level or electron shell denoted as 'n'd = the sub-shell of the energy level (known as a degenerate level)1 = the number of electrons occupying the sub-shell.Through extensive research by scientists, no known element has a d sub-shell in the second (n=2) energy level. In fact, the d sub-shell does not appear until the fourth period (fourth row).The first d sub-shell is known to be in the third energy level (therefore the first energy level with this sub-shell is 3d, but not 2d).Transition metals are the elements known to fill the d sub-shells. The first transition metal in the periodic table is scandium (Sc) with the electron configuration of [Ar]4s23d1.The reasons for the formation of sub-shell of d is beyond my knowledge and the scope of basic chemistry.
