Q: What is the most
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%. Oxygen is the third-most abundant element in the universe.
Iron is the most abundant element, by mass, in the Earth, constituting about 80% of the inner and outer cores of Earth.
Detailed Solution. The second most common element in the Earth is Silicon. Only the hydrogen element is found in the universe in larger amounts. The chemical composition of Earth is different from that of the universe.
Carbon is the fourth most abundant element in the observable universe and the 15th most common in the Earth's crust.
Since the oceans are mostly water, the elements hydrogen and oxygen are the most common.
Answer and Explanation: The amount of gold present in the earth's crust is 0.001 to 0.006 parts per million. The amount of gold per 4000 meters on the surface is 35 billion tons of gold.
Silicon makes up 27.7% of the Earth's crust by mass and is the second most abundant element (oxygen is the first). It does not occur uncombined in nature but occurs chiefly as the oxide (silica) and as silicates. The oxide includes sand, quartz, rock crystal, amethyst, agate, flint and opal.
More than 90 percent of Earth's mass is composed of iron, oxygen, silicon, and magnesium, elements that can form the crystalline minerals known as silicates. Nevertheless, in chemical and mineralogical composition, as in physical properties, Earth is far from homogeneous.
The chemical composition of the earth is quite a bit different from that of the universe. The most abundant element in the earth's crust is oxygen, making up 46.6% of the earth's mass. Thulium is the least abundant element.
The oldest chemical element is Phosphorus and the newest element is Hassium. Please note that the elements do not show their natural relation towards each other as in the Periodic system.
Hydrogen is the most abundant element in the Universe and helium is second. Together they make up roughly 74% and 24% of all matter in the universe respectively.
Each element is assigned a symbol - H for hydrogen. You should learn the symbols for the eight most abundant elements in the Earth's crust (Oxygen (O), Silicon (Si), Aluminum (Al), Calcium (Ca), Iron (Fe), Magnesium (Mg), Sodium (Na), and Potassium (K) .
The United States holds the largest stockpile of gold reserves in the world by a considerable margin at over 8,100 tons. The U.S. government has almost as many reserves as the next three largest gold-holding countries combined (Germany, Italy, and France).
Although the Earth's crust averages a mere 0.004 grams of gold per ton, commercial concentrations of gold are found in areas distributed widely over the globe. Gold occurs in association with ores of copper and lead, in quartz veins, in the gravel of stream beds, and with pyrites (iron sulfide).
We do know that gold makes up about four parts per billion of the earth's crust. What we don't know, however, is precisely how much gold is still out there. The WGC estimates that there are 54,000 tonnes of “below-ground gold reserves” waiting to be mined.
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.
By mass, the Earth is composed of mostly iron (35 percent), oxygen (30 percent), silicon (15 percent), and magnesium (13 percent). It is made of distinct layers: a thin crust, upper mantle, lower mantle, outer core, and inner core, as well as transition zones.
Four of these elements (hydrogen, carbon, nitrogen, and oxygen) are essential to every living thing and collectively make up 99% of the mass of protoplasm. Phosphorus and sulfur are also common essential elements, essential to the structure of nucleic acids and amino acids, respectively.
Planetary scientist and stardust expert Dr Ashley King explains. 'It is totally 100% true: nearly all the elements in the human body were made in a star and many have come through several supernovas. '
The human body is approximately 99% comprised of just six elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Another five elements make up about 0.85% of the remaining mass: sulfur, potassium, sodium, chlorine, and magnesium. All of these 11 elements are essential elements.
Hydrogen is the most abundant element in the universe and oxygen is the most abundant gas in the earth's crust. Hydrogen is the main component in the sun and the stars.
