Suppose you could see a 2s subshell and a 2p subshell. How could you tell them apart?
You can differentiate between a 2s and a 2p subshell based on their shape. The 2s subshell is spherically symmetric and has one orbital. On the other hand, the 2p subshell has a dumbbell shape and consists of three orbitals: px, py, and pz, each oriented along separate axes.
How many electrons are in the second energy of the atom?
According to the Bohr's atomic model the number of electrons present in a orbit can be defined by p(n.n) i.e p.n square,where n=number of orbit.hence we can calculate the number of electrons present in second orbit i.e 8.
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 does the third quantum number (l) describe?
The specific orbital within a sublevel- apex
How many total electrons does an atom possess if it has the first two electron orbitals completed?
4 electrons. First orbital is the 1s which has 2 electrons. Second orbital is the 2s which has 2 electrons.
Why is transfer of electron from 2s subshell to 1s subshell not possible?
For a 2s subshell to be present, the 1s subshell must first be full, which means no more electrons can be moved into the 1s subshell.
In what atoms is the 2s orbital closest to the nucleus?
The electrons in the 2p subshell have more energy than those in the 2s subshell, that is energy per electron.See Wikipedia 'Electron Shells' for more on this subject.

Why is the 2s subshell of heigher energy than the 1s subshell?
it is just a quantum property, its further away from the nucleus
What element has 2 electrons in the 1s sublevel and 4 electrons in the 2s level?
An element cannot have 4 electrons in the 2 s level. The s subshell can hold only TWO electrons. Carbon has 4 electrons in the 2p level, however, if that's what you meant.
How can you tell the difference between 2s subshell and 2p subshell?
You can tell the difference between 2s sub-shell and 2p sub-shell by checking their energy levels whereby a 2p orbital has a higher energy level compared to a 2s orbital.

Actually carbon valency written as 1s2 2s2 2p2.why not this is write as 1s2 2s1 2p3?
First of all this is not Carbon's valency, it is electronic configuration or arrangement of electrons around nucleus. Electron filling takes place by Aufbau principle. Explanation: Electrons around an atom are arranged in shells( denoted by n) numbered 1, 2, 3, and so on. Each of these shells is further divided into s,p,d,f subshells(denoted by l). It is known that electrons in a subshell have same energy. Electron filling occurs 1st in subshells of lower energy and higher energy subshell is filled only after the lower subshell is completely filled (Aufbau principle). Subshell whose n+l sum is less has lower energy. So here 2s(n+l=2) shell is lower to 2p(n+l=3), and 2s can have 2 electrons so after 2s is filled 2 electrons left go to 2p subshell.
How many f orbitals have n 6?
There are 2, the 2s and 2p subshells. The s subshell contains just one orbital and can hold only two electrons (of opposite spin) The p subshell contains 3 orbitals each of which can hold just 2 electrons (of opposite spin) making 6 electrons in all
What types of electrons s p d or f are considered those involved in the make up of the outer shells of atoms?
It depends on the particular atom in question. Any of those subshells can make up the outer shells of atoms. Examples: In Mg, the outer shell is the 2s subshell. In P, the outer shell is the 3p subshell. In Fe, the outer shell is the 3d subshell, etc.
If each orbital can hold a maximum of two electrons how many electrons can 2s hold?
