Leg Weakness â Causes and Treatment. Leg weakness is a serious symptom which is commonly ignored by many people. Leg weakness is highly based on ones own perception, so many people may not even realize that they have leg weakness. However, for practical purposes it is the first sign of paralysis because of nerve compression in the lower back. Leg weakness is frequently accompanied by loss of touch sensation and shooting pain, which generally come before the leg weakness.
Description: Arsenic's name comes from the Greek term for an arsenic compound, orpiment (arsenic trisulfide). Arsenic is a metalloid element, which, like phosphorus, has two main forms. One is a brittle, gray metallic form and the other is a yellow, non-metallic solid.Yellow arsenic is the more reactive and unstable of the pair. Arsenic is stable, being unaffected by air, water, most acids and alkalis.Arsenic has no liquid phase; the solid sublimes directly into a vapor.rsenic has semiconductor properties and is used in making transistors. It is also used in alloys, glass production, pyrotechnics and wood preservatives. An arsenic-gallium compound is used in making lasers.
Because arsenic is an element like carbon and oxygen it does not break down in the environment into simpler substances-though it can change form and combine with other elements into molecules that have different chemical properties. Some forms of arsenic are quite toxic; others are less so.
