Trace Element
Oranges contain a variety of chemical elements, with the most abundant being carbon, hydrogen, and oxygen. They also contain smaller amounts of minerals such as potassium, calcium, and magnesium. Additionally, oranges contain trace amounts of elements such as iron, zinc, and copper.
No elements are organic. Molecules can be organic, and are those that are comprised mainly of carbon, hydrogen and oxygen (and sometimes nitrogen and small amounts of other elements). However, only molecules made from combinations of these elements can be considered to be organic, the elements by themselves are not!
Micro elements are those that are needed in very small amounts by the body. Some examples are: zinc, iodine, manganese, copper, selenium, and iron. Macro elements are those that are needed in larger amounts in the body. Examples are: phosphorus, magnesium, potassium, sodium, and calcium. There is a third group, called toxic elements, that should not be in the body. Examples are aluminum, thallium, mercury, cadmium, and lead.
Life as we know it requires carbon, oxygen, nitrogen and smaller amounts of other elements. Those elements are needed in particular forms. The only planet where they exist in the amounts needed is earth. The proper ratios may exist in an extremely small amount on Mars. So far no life has been found on Mars. Suggestions have been made that life could be based on ammonia or some other compound instead of water. So far it has not been found.
There is no known naturally occurring element that is not on the periodic table of elements. Occasionally elements are created in laboratory experiments that have a higher number of protons than those on the periodic table. These elements tend to be around for a very short time. There are expected to be heavier elements that have not yet been confirmed to have been produced. There is some reason to expect some of those not yet made will be stable, and its possible that one or more might be found to occur naturally in trace amounts as it was eventually discovered Plutonium is. But you'll probably be out of school before then...
The gaps were left for elements which were not discovered at that time. The properties which were estimated for the elements at that time was same as found later in those elements.
Well, the fact that you said "trace elements" makes me think you probably don't mean hydrogen or helium, which are present in large amounts in stars.After those, the three most common elements would be oxygen, carbon ... and then it gets complicated. Most probably the third would be neon, but iron and nitrogen are also pretty common.
Yes, the elements found in magma can be different from those found in Earth's crust. Magma can contain a higher concentration of elements like silicon, aluminum, magnesium, iron, and calcium compared to the crust, as these elements are more common in the mantle where magma is primarily formed. Additionally, the process of partial melting and differentiation can lead to variations in element composition between magma and the crust.
Because it is intended to represent all known elements, not only those which exist in nature.
Minerals are grouped as macrominerals and trace minerals. Macrominerals are those found in larger quantities in the body and needed in larger amounts in the diet. Calcium and phosphorus are two of the seven macrominerals that we need in our diets.Trace minerals are found in small quantities in the body and are needed in small amounts in the diet. We need to include nine trace minerals in our diets, including iron and zinc.The following table lists the 16 minerals that we need in our diets.Table 1.Types of MineralsMacromineralsTrace MineralsSodiumIronPotassiumZincChlorideIodideCalciumSeleniumPhosphorusCopperMagnesiumFluorideSulfurChromiumMolybdenumManganese
Hydrogen, oxygen, carbon,Argon, nitrogen, sodium, chlorine, fluorine, calcium, and sulphur Those are some of the more important elements.
well some of the nature elements are known as Fire, Water, Earth, and Air Another answer I think what you may mean is what elements (chemical elements - not those in the answer above) are found in an uncombined form in nature. Well, not many. Gold is one. Nitrogen gas, oxygen, all the inert gases are others
