- Bohr Diagrams 1) Check your work. 2) You should have 6 total electrons for Carbon. 3) Only two electrons can fit in the 1 st shell. 4) The 2 nd shell can hold up to 8 electrons. 5) The 3 rd shell can hold 18, but the elements in the first few periods only use 8 electrons. C
- Carbon tetrafluoride may be made by direct reaction between carbon and fluorine. Charcoals are not suitable as higher weight carbon fluoride form. The reaction can be carried out in a copper tube. Impurities in the gaseous product may be removed by fractional distillation. Carbon tetrafluoride melts at -183.6°C and boils at -127.8°C.
Bohr Model Diagrams Bohr model diagrams show the number and arrangement of electrons in an atom or ion. 0 Electron arrangements are in the pattern 2, 8, 8, 18 for the first 36 elements. How Valence Electrons Relate to Chemical Families Elements in the same chemical family have the same number of valence electrons.
- Draw Bohr diagrams for the following: 1 a helium atom 2 a carbon atom Identify how many valence electrons are present in each. Include the number of protons and neutrons in the nucleus. Unit 2 - Atoms and Elements 4 / 14
Examples of Bohr-Rutherford Diagrams: Carbon: # protons = atomic number = 6 # neutrons = atomic mass – atomic number = 12–6 = 6 # electrons = # protons = 6 Aluminum: # protons = atomic number = 13 # neutrons = atomic mass – atomic number =27-13= 14 # electrons = # protons = 13
- Example: the carbon atom. Rutherford-Bohr diagram Lewis notation If an element has more than four valence electrons, they are doubled to form pairs of dots around the element. For example, neon is represented by eight valence electrons. Rutherford-Bohr diagram Lewis notation SAMPLE QUESTIONS:

- Bohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon here) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron ...

The Bohr effect allows the steady release of this bound up oxygen throughout the body while the blood is delivered to the other parts of the body such as the fingers and toes. You see our pH in the lungs is around 7.4. As the blood moves through our body our pH is changed to around 7.2 because the blood picks up carbon dioxide.
