Oxygen (O) , Cabon (C) , Hydrogen (H) , and Nitrogen (N) make up about 96% of the living matter in your body. That question is literally answered on the page before those 3 questions
The correct order according to decreasing size of structures is organism > organ system > organ > tissue > cell > organelle > molecule.
The four elements that make up about 95% of the human body and other organisms are oxygen, carbon, hydrogen, and nitrogen. These elements are essential for various biological processes such as respiration, metabolism, and building macromolecules like proteins and DNA.
To determine the order of elements in a molecular formula, consider the standard conventions: carbon is typically listed first, followed by hydrogen, then other elements in alphabetical order. It is important to know the symbols and names of elements to correctly identify their order in a formula.
The decreasing order for the relative strengths of chemical bonds is: covalent bonds, ionic bonds, and hydrogen bonds. Covalent bonds are the strongest, formed by the sharing of electrons, followed by ionic bonds where electrons are transferred, and hydrogen bonds are the weakest, formed by the attraction between polar molecules.
By molar amount, hydrogen and oxygen are the most common elements; carbon is the third. By mass, oxygen is the most common, and carbon is the second (with hydrogen being third by mass). By mass, oxygen is the most abundant, and phosphorus is the least, carbon the 2nd, hydrogen, 3rd. By atoms, hydrogen is most abundant, and phosphorus the least, oxygen 2nd, carbon 3rd.
No. The elements are arranged in order of increasing atomic number.
The list would include elements such as fluorine, chlorine, bromine, iodine, and astatine. These elements belong to the halogen group and exhibit decreasing chemical reactivity from top to bottom due to increasing atomic size and decreasing electronegativity.
Elements vary in their ability to conduct electricity. From most conductive to least conductive in relative terms are (all figures are measured in cm ohm) silver at 0.63 10^6, copper at 0.596 10^6, and gold at 0.452 10^6.
The question is ambiguous. It isn't clear if by "world" you mean the observable Universe, or our planet Earth. The abundance varies. For instance, in Earth's crust (i.e., the part we can easily access), the most abundant elements are oxygen, silicon, and aluminium - in that order.
The two most abundant elements in the human body are oxygen and carbon. Oxygen makes up about 65% of the body's mass, while carbon makes up about 18%.
In no particular order, carbon, hydrogen, oxygen, nitrogen
The three main isotopes, in decreasing order of abundance, as 40Ar, 36Ar and 38 Ar.
The top three elements in Earth's atmosphere are nitrogen (78%), oxygen (21%), and argon (0.93%). These three elements together make up the vast majority of the gases present in the atmosphere, with nitrogen being the most abundant.
The most abundant elements in the universe, in order from most to least abundant, are Hydrogen, Helium, Oxygen, Carbon, and Nitrogen. Therefore, the correct list would start with Hydrogen, followed by Helium (not listed), then Oxygen, Carbon, and finally Nitrogen. The first option you provided, "Hydrogen Oxygen Nitrogen Carbon," is almost correct but is missing Helium and has an incorrect order for Nitrogen and Carbon.
The ranking of radicals in order of decreasing stability is as follows: benzyl allyl tertiary secondary primary methyl.
