Magnesium is a chemical element with symbol Mg and atomic number 12. Classified as an alkaline earth metal, Magnesium is a solid at room temperature.

Liquid metal is a metal or a metal alloy which is liquid at or near room temperature. A few elemental metals are liquid at or near room temperature. The most well known is mercury (Hg), which is molten above −38.8 °C (234.3 K, −37.9 °F).

Solids: particles vibrating in a fixed regular geometric pattern. (Crystal lattice structure) Most elements exist as solids at STP. Most metals are solids at STP except for Mercury. Metalloid solids- B, Si, Ge, As, Sb and Te.

As a pure element, iodine is a lustrous purple-black nonmetal that is solid under standard conditions. It sublimes (changes from a solid to a gaseous state while bypassing a liquid form) easily and gives off a purple vapor. Although it is technically a non-metal, it exhibits some metallic qualities.19

According to TIMES, Stanford economists Stefanos Zenios and colleagues have demonstrated that the average value of a year of quality human life is about $129,000. It concludes that the grand total of material cost for a typical human body is a meager $160. The result: theoretically, your body worths up to $45million.27

Nitrogen – 2.4kg The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.

Inhalation: High concentrations of this gas can cause an oxygen-deficient environment. Individuals breathing such an atmosphere may experience symptoms which include headaches, ringing in ears, dizziness, drowsiness, unconsciousness, nausea, vomiting and depression of all the senses.

Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water….

It would be impossible for life on earth to exist without carbon. Carbon is the main component of sugars, proteins, fats, DNA, muscle tissue, pretty much everything in your body. As the most stable thing for an atom to have is eight electrons, this means that each carbon can form four bonds with surrounding atoms….

Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

Each element bonds to oxygen. But when carbon oxidizes–or unites with oxygen say, during burning–it becomes the gas carbon dioxide; silicon oxidizes to the solid silicon dioxide, called silica. The fact that silicon oxidizes to a solid is one basic reason as to why it cannot support life.

The answer lies with carbon’s unique properties. Carbon has an exceptional ability to bind with a wide variety of other elements. Carbon makes four electrons available to form covalent chemical bonds, allowing carbon atoms to form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen.
