C, H, N, O
A way to know what this means is to know that the reason being is because it is a Isotope. An istotope is something that has too many nuetrons or more than one nuetron. So that is what they call it...
there is no such thing as the four elements that make up the world... this was believed in ancient times... these four elements were wind, fire, earth and water but now since we hav e developed and now have a greater undertanding of the world we live in we have discovered that there are alot of "real" elements that make up the world
short answer outside of an entire degree in biology would be they permit the structure and chemical reactions of life.
It depends on the elements! If two of them are carbon and hydrogen, hundreds of compounds can be made from these elements alone. If the four elements are all noble gases, no new substances can be made from them by chemical reaction.
Those four elements are carbon, hydrogen, oxygen, and nitrogen (sometimes known collectively as CHON).
or livind things
All the elements listed on periodic table has symbols for them.There are total 118 elements in periodic table.
H = Hydrogen, C = Carbon, O = Oxygen, and N = Nitrogen. These are the Symbols for these four "proteinaceous" Elements.
The four elements you will find in an elements box are Water, Fire, Air, and Soil
everything
Hard to say since you're not mentioning the four elements.
A square typically symbolizes stability, structure, order, and balance. It can also represent honesty, reliability, and groundness.
Carbon, Hydrogen, Nigtogen, Oxygen, Phosphorous and Sulphur are the six elements that make up 95% of living things.
CHON - carbon, hydrogen, oxygen, & nitrogen.
