The electron configuration for mercury is this: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p6 4f14 5d10 6s2 Mercury is element 80. That's its atomic number, and there are 80 protons in its nucleus. If a mercury atom is neutral, it will have 80 electrons about it, and the electrons will be arranged as outlined above.
There are 18 electrons in total, and the outer energy levels are the 4s and 3d orbitals. Therefore, there are 2 electrons in the 4s orbital and 4 electrons in the 3d orbital, making a total of 6 electrons in the outer energy levels.
Argon has 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level.
Most elements have multiple energy levels, typically ranging from 1 to 7. The number of energy levels an element has depends on the number of electrons it contains. Each energy level corresponds to specific electron orbitals where electrons can be found.
Electrons jump energy levels when they absorb or emit a photon of specific energy that matches the energy difference between the levels. This process is governed by the principles of quantum mechanics.
Hydrogen has one core electron. Core electrons are those in the inner energy levels of an atom and are not involved in chemical bonding.
Mercury has 2 electrons in its outer level, which is the 6th and final energy level for mercury.
Two electrons can be housed in the first energy level.
