The Main Answer is: 1.) Sodium

                                    2.) 11 electrons

                                    3.) L shell

                                    4.) 8 electrons

Given: A Lewis dot structure of an atom

To Find: 1. Identify the element.

              2. How many electrons are there?

              3. Name the second cell of the atom.

              4. How many electrons are there in this shell​?

Solution:

1.)

  • The given structure of the atom has been labeled as "Na".
  • This is the chemical formula for Sodium metal.
  • Also, there are a total of 11 electrons present in the atom.
  • As the no. of electrons = no. of protons = 11
  • The atomic no. (no. of protons) for the given atom = 11
  • And the element with atomic no. 11 is Sodium.

2.)

  • As mentioned above, on counting, one can find that the number of electrons in the given atom = 11

3.)

  • In general, the shells of any atom are labeled as K, L, M, N, and so on; where K = 1st shell, L = 2nd shell, and so forth.
  • Therefore, here, the second shell of the atom is the L shell.

4.)

  • In the L shell, in this atom, there are 8 electrons and it has reached its maximum capacity.
  • The maximum no. of electrons that a shell can accommodate = 2n²; where n = shell number, in this case, n = 2.
  • ∴ Max capacity = 2 × 4 = 8.

Therefore, the final answers are: 1.) Sodium

                                                         2.) 11 electrons

                                                         3.) L shell

                                                         4.) 8 electrons
