This electron shell is near the atomic nucleus.
The sub-level s of energy that make the o shell is the K-shell.
first energy level contains only S shell that can accomadate 2 electrons where as 2nd energy level contains S shell and P shell as well which can accomadate 2 and 6(3X2) electrons respectively..so the answer is 8 for 2nd energy level. (or) No.of electrons in any main energy level = 2n2 Here n = orbit (or energy level) number In our question , n = 2 No.of electrons in 2nd energy level = 2(2)2 = 8
Electrons
Each shell represents a distinct state of electron energy.
This electron shell is near the atomic nucleus.
The sub-level s of energy that make the o shell is the K-shell.
Actually each energy level is considered to be a shell and the electrons are moving in the shell (in fixed paths).
Shell or energy level corresponds to the shell in which the electrons are present.
The outermost energy level of an atom is referred to as the valence shell.
Each electron shell corresponds to a different principle energy level. Each shell can contain only a fixed number of electrons.
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
the energy levels are as follows: first shell 2 second shell 8 third shell 5
is a level of bad energy that is confined spatially can only take on certain discrete values of energy.
The K shell's 1s orbital is te first energy level of an electron.
These are the valence electrons.
electrons are found in pairs
