Nitrogen, sulfur, and halogens are often referred to as foreign elements because they do not belong to the main group of elements typically found in biological systems or common geological processes. They can be present in trace amounts but are not essential for the basic biochemical functions of most organisms. Their presence can indicate environmental contamination or unusual geochemical conditions, thus being termed "foreign" in that context.
Phosphorus complexes are present in proteins but is not present in sugars or fats..
Sulphur
Sulphur...
No, sulfur is an element and sulfur dioxide is a gaseous compound. Sulfur dioxide is the combustion product of sulfur in an oxygen atmosphere (S+O2 --> SO2) Where sulfur is an element, sulfur dioxide is a compound and where sulfur is an insoluble yellow solid, sulfur dioxide is a colorless soluble gas.
There is no specific element with the symbol SCN on the periodic table. SCN commonly refers to the thiocyanate ion (SCN-) which is a polyatomic ion. It is a combination of sulfur (S), carbon (C), and nitrogen (N), commonly found in compounds.
Organic compounds may contain other elements than carbon, hydrogen and oxygen such as nitrogen ,halogen, sulphur, etc....these elements are known as foreign element.
Sulphur, silicon and phosphorus.
Phosphorus complexes are present in proteins but is not present in sugars or fats..
a sulphur element has no mobile electrons
Sulfur (also spelled sulphur) is an element.
Sulfur, also spelled sulphur, is an element.
Nitrogen is a non-metallic chemical element essential for life and found in proteins and DNA, while sulphur is also a non-metallic element used in various industrial applications and as a component in some amino acids. Nitrogen is a gas at room temperature, while sulphur is a solid. Both elements play important roles in biological and industrial processes.
Sulphur is a pure element.
Sulphur and Oxygen
You shouldn't find nitrogen or sulphur in carbohydrates. Carbohydrates only contain carbon, hydrogen and oxygen.
No, hydrogen is not a halogen. the 17th column on the periodic table is called halogen column. both halogens and hydrogen are diatomic elements, but the difference is that halogens have ionic charge of minus 1. But, hydrogen can have either ion charge of plus 1 or minus 1. hope that helps
Nitrogen is a chemical element found in the atmosphere and essential for living organisms to build proteins and DNA. Sulfur is another element found in nature, used in the production of various compounds including sulfuric acid and amino acids. Both nitrogen and sulfur play important roles in various chemical and biological processes.
