As you can see, the first floor of f Tower is higher than the first floor of d Tower, which is higher than the first floor of p Tower, etc. If electrons want to move to a higher energy level, they have to GAIN energy! If electrons want to move to a lower energy level, they have to LOSE energy!Įlectron Proton Neutron Hydrogen-1 Helium-4 Lithium-6 1 p 0 n 1 e p 2 n 2 e p 4 n 3 eĥ Examples Draw Bohr model diagrams for the following elements.Ħ Electron Hotel f Tower Seven rooms per floor d Towerįloor 3 CLOSED Floor 2 CLOSED Floor 2 CLOSED The electron hotel is adapted from Kelly Deter’s revised PowerPoint presentation for Chemistry You Need to Know Chapter 4, section 3 Floor 1 CLOSED f Tower Seven rooms per floor Floor 1 CLOSED d Tower Five rooms per floor Floor 1 CLOSED p Tower Three rooms per floor s Tower One room per floorħ Electron Hotel The hotel is also built on a hill. (This will be explained later.)ģ Bohr Model Revisited-convenient way to show electrons in energy levels BE CAREFUL: At first, only 8 electrons enter the 3rd block, then 2 in the 4th and then any other remaining will enter back into the 3rd energy level. of 8 electrons, the 3rd can hold a maximum of 18, and the 4th level a maximum of 32. of 2 electrons, the 2nd level can hold a max. It consists of the nucleus with protons & neutrons and electrons in concentric orbits (circles) outside the nucleus The circle closest to the nucleus contains the lowest energy electrons The 1st level can hold a max.
