h
The element name for element number 31 is Gallium.
Pentane has five carbon atoms, so it will have 12 hydrogens attached to these carbon atoms. Additionally, pentane has two hydrogens at the ends of the molecule, giving a total of 14 hydrogens.
Ribose has 10 hydrogens and 5 oxygens.
I guess you mean the number "2" in O2. It is the valency of oxygen which means oxygen can have two single bond (hydrogens) with two other elements or a single double bond with an element. A good example methane-CH4, here single carbon atom paired with four hydrogens with four single bonds.
To add hydrogens to a molecular structure using PyMOL, you can use the "hadd" command followed by the selection of the atoms you want to add hydrogens to. This command will automatically add hydrogens to the selected atoms in the molecular structure.
hydrogen
Ammonia is NH3 So it contains one nitrogen and three hydrogens
Chlorophyll is not an element. it is a compound. It has 55 carbons, 72 hydrogens, 1magnesium, 4 nitrogen and 5 oxygen elements in it. Its' formula is C55H72MgN4O5.
Hydrogens, then Carbons, then anything else. For instance: H3C(OH)
Neither. A non-metal element has no charge, which would be required for attraction.
Hydrogen is a non metal element. Atomic mass number of it is 12.
Hydrogen is the most abundant element in the universe, but it is relatively rare in the Earth's atmosphere. It makes up only about 0.000055% of the atmosphere by volume.
There are 24 hydrogens in the molecular formula C22H ClN2O2.
Single proton orbited by a single electron (standard isotope in non-ionized state). Most abundant element in the universe, highly reactive.
