Therefore, which of the following is most correct about an atom of neon? Because shell two has eight electrons it is now full. The atomic number of oxygen is 8 with electronic configuration as 1s2 2s2 2p4. You can find the number of neutrons if you know the isotope of the atom. If the charge is negative, electrons are in excess. of protons=no.of electrons. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The chemical symbol for Neon is Ne. The first two electrons go into the 1s shell-subshell combination. So we "build up" from the previous electrons by adding one more. How do I … Chlorine is the only atom of the three atoms present to have the third principal quantum shell (3) which contains 7 electrons. Unfortunately, the mass number isn't listed on the Table of Elements. Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure.
