1.) They move in and out of living systems.
certain elements naturally occur in pairs, called diatomic elements: Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, and i believe Iodine. Ie. in nature, you never see a nitrogen by itself.
activity series
Yes. Compounds can undergo chemical changes to become elements. An example would be the following: Zn(s) + CuCl2(aq) ===> ZnCl2(aq) + Cu(s). THe CuCl2 is a compound and it is changed into the element Cu(s) and also into zinc chloride.
No color or combination of colors can produce red. Red is a primary color, it stands on its own at least in painting. However its possible that certain elements in the chemical field may produce a red color.No color or combination of colors can produce red.

A compound is formed. The process may require a certain amount of energy (heat) to react, or it may release energy in the form of heat.
maintaining the balance of certain nutrients, such as nitrogen, in the ecosystem
There is chemical grouping present in all proteins, as all proteins contain certain elements. These include hydrogen, oxygen, nitrogen, and carbon.
Chemical pollution happens when certain compounds are improperly disposed of. This can affect the environment by disrupting the processes of the ecosystem.

The letters on the periodic table are the chemical symbols of the chemical elements.
Every living being is made of organic compounds. All the organic compounds contain carbon and hydrogen. Other than that, oxygen, nitrogen, phosphorus, sulphur are present in them.
The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, although other elements are found in the side chains of certain amino acids. Adenine is made of the elements carbon, hydrogen and nitrogen (C5H5N5).
True.
more electropositive element first, followed by electronegative elements
Enjoy life? There would be no life without certain elements. Carbon, oxygen, nitrogen, phosphorous and calcium, to name a few.
By lightening and by nitrogen fixing bacteria in the roots of certain plants (eg the legumes).
These elements have similar chemical properties.
