the first shell hods 2 the second shell holds 8 the third shell holds 8 the forth shell holds 16 if u look at the table it is however many are in the horizontal row
1st electron shell can hold 2 electrons; 2nd electron shell can hold 8 electrons; 3rd electron shell can hold 18 electrons; 4th electron shell can hold 32 electrons.
Shell is only Imaginary path made by rotating of the electron. A more common concept is that the shell or shape of the various orbitals is a probability density function for the election. That means...
it is the ring around the nucleus of an atom which contains electrons
in the first shell there are 2
in the second there are 8
'' '' third '' '' ''
in the outer shell there are 2
Electrons are arranged in main energy levels and then into sublevels depending on the atom. In summary: The main energy levels are given a number, the sublevels are given a letter. Each sublevel...
