### element | metal | lead:

Native lead
* is rare in nature.
* occurs in nature, but it is rare.

Pencil lead
* can be fatal if eaten.
* is attached to a removable metal surface
  - consumable products
  - graphite
  - made up of graphite, which is closely packed carbon atoms
* mixture of graphite and clay.
* works like a lubricant for keys that stick in locks.

Pure lead
* corrodes at a very slow rate compared to alloys of calcium and antimony
  - very slowly compared to a lead-calcium alloy
* heavy gray metal, easily scratched with a house key.

Liquid metal
* Liquid Metals Create a liquid chrome metallic texture.
* conducts electricity.
* provide an intermediate subphase for monolayers.
* shrinks as it solidifies, creating holes that weaken the final part.

Lithium
* Some lithiums have low power
* includes atoms.
* is metal
* works by bringing various neurotransmitters in the brain into balance.

### element | metal:

Magnesium
* can also be helpful for some migraine patients.
* can also cause loose stools in some people as it brings water into the digestive track
  - significant vasodilatation of intact cerebral arteries
  - improve sleep
  - relax nerve impulses and muscle contractions
* has all the required properties to protect the heart
  - laxative effects and helps reduce muscle contractions
  - many effects which counteract migraines
  - no effect on the tubulin-dynein system of cilia which is independent of calcium
  - only one valence
  - several important metabolic functions
  - the ability to relax nerves and muscles
* is also a Calcium channel blocker
  - viable alternative to other metal alloys
* is also essential for the health of the heart and the circulatory system
  - production and utilization of insulin
  - necessary for healthy bones and energy production
* is also necessary for the metabolism of vitamin C, phosphorus, potassium and sodium
  - production of parathyroid hormone
  - lighter than even aluminum, yet about as strong
* provides many benefits for the heart.
* seems to affect everything from breathing patterns to reflex muscle tension.

### element | metal | magnesium:

Dietary magnesium
* Most dietary magnesium comes from vegetables, particularly dark-green leafy vegetables
  - such as dark green, leafy vegetables
* affects susceptibility of lipoproteins and tissues to peroxidation in rats
  - tisue to peroxydation
* is absorbed in the small intestines and is excreted through the kidneys.

Intracellular magnesium
* is correlated with intracellular potassium.
* predicts functional capacity in patients with coronary artery disease.

Low magnesium
* causes abnormal heart rhythm and convulsions
  - tissue breakdown and cell destruction
* is associated with cardiovascular problems, depression, and anxiety.

Magnesium citrate
* is also an easily absorbed form of magnesium
  - chemical compounds
  - more soluble and bioavailable than magnesium oxide
* very absorbable form.

Magnesium supplementation
* can decrease the size of an existing stone and prevent further formations
  - lower blood pressure in people with hypertension
* is beneficial as well, working with the oils to reduce inflammation
  - especially beneficial during times of extreme stress or illness
  - one of the latest and greatest supplements for headaches
  - used widely in Canada as a preventive regimen
* reduces the development of diabetes in a rat model of spontaneous niddm.

Manganese metal
* dissolve in acid and corrode in moist air.
* is ferromagnetic only after special treatment.
