Study Notes
Blood and Microhematocrit Tubes
- Blood enters and rises in a microhematocrit tube due to capillary action, which pulls the blood into the narrow tube.
- This action is enhanced by the surface tension of the blood and the affinity of blood components to the tube's surface.
Anticoagulants in Microhematocrit Tubes
- Coating agents, such as heparin or EDTA, serve as anticoagulants on the surface of microhematocrit tubes, preventing coagulation.
Element Square on the Periodic Table
- An element square provides essential information, including the element's atomic number, symbol, name, and atomic mass.
Group 18 Elements
- Group 18 of the periodic table is known as the noble gases, which include helium, neon, argon, krypton, xenon, and radon.
Rows of the Periodic Table
- Rows of the periodic table are referred to as periods, which represent elements with increasing atomic numbers and properties.
Valence of Halogens
- Halogens have a valence of -1, indicating they have seven valence electrons; they require one additional electron to complete their outer shell.
Neutral Atoms and Electrons
- In a neutral atom, the number of electrons is equal to the number of protons, maintaining electrical neutrality.
Octet Rule Fulfillment
- Most atoms seek to fulfill their octet rule by having eight electrons in their valence shell for stability, typically achieved through bonding.
