What is the difference between beryllium and magnesium?
Beryllium can be thought of as being even more covalent than magnesium. The small size (ca. 0.3 Å) results in a very high charge density of Be2+….Beryllium.
| M | Structure |
|---|---|
| Be | Polymer (4-coordinate Be) |
| Mg | Cadmium chloride structure (6-coordinate Mg) |
| Ca | Deformed rutile structure (6-coordinate Ca) |
Which is more metallic beryllium or magnesium?
The alkaline-earth metals tend to lose two electrons to form M 2+ ions (Be2+, Mg2+, Ca2+, and so on). These metals are less reactive than the neighboring alkali metal. Magnesium is more active than beryllium; calcium is more active than magnesium; and so on.
How is beryllium used in everyday life?
Beryllium is used in gears and cogs particularly in the aviation industry. Beryllium is a silvery-white metal. It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools.
How dangerous are magnetrons?
Magnetrons can be incredibly dangerous, while you are safe from radiation when they are not powered, the ceramic insulators can contain beryllium oxide which can be fatal when inhaled. If Magneto is the enemy of the X-Men, the magnetron is the enemy of all lungs everywhere.
Why is microwave repair dangerous?
It could be EXTREMELY DANGEROUS to operate a microwave oven with the cover off, much more dangerous even than working on raw mains electricity. An improper repair could lead to potentially dangerous leakage of microwave energy.
How long does it take a microwave capacitor to discharge?
The time to discharge to a safe voltage will be on the order of several 10s of seconds if the internal Resistor is 10 megohms and the Capacitor is less than 1 microfarad. The cap should be dead if you allow your microwave to sit overnight.
