18 electrons maximum
The 3rd energy level of an atom can hold a maximum of 18 electrons.
The first energy level of an atom can hold a maximum of 2 electrons.
The third energy level of an atom can hold eight electrons.
The atom will have 3 energy levels. The first energy level can hold up to 2 electrons, the second level can hold up to 8 electrons, and the third level can hold the remaining electron.
K,L,M,NN is the fourth shell. It can hold a maximum of 32 electrons.2n2 is the maximum electrons for the energy level (n).
There six electrons in carbon atom, 2 in the first shell and 4 in the second shell.
The 3rd energy level of an atom can hold a maximum of 18 electrons.
The first energy level of an atom can hold a maximum of 2 electrons.
5
The atomic number of iodine is 53. So there will be 53 protons in the nucleus. For iodine atom to be neutral there will 53 electrons in total.
