- completely transfer electrons). On the right is an image of water's molecular structure. Water is the most abundant molecule on Earth. Approximately 70% of the Earth's surface is water. Water is also the only substance on Earth which naturally occurs in a solid, liquid and gas form. The Celsius temperature scale is based on waters' freezing point (0 degrees) and boiling point (100 degrees). Unlike most substances, water's solid from is less dense than its liquid form - this is why ice

Oxygen: the essentials Oxygen gas (dioxygen, O 2) makes up 21% of the atmosphere by volume. It is the most abundant element in the earth's crust (followed by silicon). It is present in any number of minerals and makes up most of the weight of water. Oxygen is the third most abundant element found in the sun, and is involved in the carbon-nitrogen cycle, one of the processes responsible for stellar energy production. The atmosphere of Mars contains about 0.15% oxygen.

- Hydrogen is the lightest, simplest and most commonly found chemical element in the Universe, making up around 75% of its elemental mass. Hydrogen is found in large amounts in giant gas planets and stars, it plays a key role in powering stars through fusion reactions.Hydrogen is one of two important elements found in water (H 2 O). Each molecule of water is made up of two hydrogen atoms bonded to one oxygen atom.In 1766, during an acid metal reaction, Henry Cavendish first formally recognized hydrogen.In 1781 he also found that hydrogen produces water when burned.ydrogen can exist as a liquid under high pressure and an extremely low temperature of 20.28 kelvin (−252.87°C, −423.17 °F). Hydrogen is often stored in this way as liquid hydrogen takes up less space than hydrogen in its normal gas form. Liquid hydrogen is also used as a rocket fuel.

Oxygen Element Facts Source: Oxygen is the most abundant element in the Earth’s crust, accounting for almost half of it by mass. More than half of the atoms in the Earth’s crust are oxygen atoms. About 86 percent of the mass of Earth’s oceans is oxygen – mainly in the form of water. Oxygen is the third most common element in the Universe, behind hydrogen and helium. It is obtained commercially from liquefied air separation plants. It can be prepared in the laboratory by electrolysis of water. Isotopes: 13 whose half-lives are known, with mass numbers 12 to 24.

6 reasons Ford picked Mexico for a new plant Last year, Ford built 2.5 million cars and trucks in the U.S. — more than any other automaker. Since 2011, Ford has invested $10.2 billion in its U.S. plants. And over the next four years, will invest $9 billion more. That investment is expected to create or retain 8,500 U.S. jobs. Last year, Ford invested $168 million at its Ohio Assembly plant to build heavy-duty trucks at that plant that were previously made in Mexico.

- Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water. It is present as a gas in the atmosphere only in tiny amounts – less than 1 part per million by volume. Any hydrogen that does enter the atmosphere quickly escapes the Earth’s gravity into outer space.

- A radio wave can have an energy of around 4 x 10-10 eV-a gamma-ray can have an energy of 4 x 109 eV. That's an energy difference of 1019 (or ten million trillion) eV! We already know that when we talk about wavelength, we are talking about the distance between two peaks of a wave.lectromagnetic waves can be described by their wavelengths, energy, and frequency. All three of these things describe a different property of light, yet they are related to each other mathematically.

Water and living organisms Water is a molecular compound, with molecular formula H2O. The atoms in a water molecule are held together by strong covalent bonds. These are very difficult to break. The dot-and-cross diagram for a water molecule shows there are two bonding pairs of electrons and two non-bonding pairs of electrons.
