a water molecule is made up of what
All monoatomic gases. For example Helium(He) does not form a  molecule(He2).Because the stabilization due to bonding  electrons=destabilization due to antibonding electrons …in its  molecular orbital model, or simply bond order(B.O)=0. For …example water is made up of the  molecule H2O . . . 2 atoms of hydrogen and 1 atom of oxygen for a  total of 3 atoms; however, there is also a substance called  Deuterium or 'heavy' water that is made of 2 double-heavy atoms of  hydrogen and 1 atom of oxygen, but it still contains the same  number of atoms: 3. A steroid that forms an essential component of animal cell membranes and acts as a precursor molecule for the synthesis of other biologically important steroids, synthesized in the liver and obtained from diet. In combining to form a compound, the entire parent materials may not be fu…lly incorporated into the compound - there may be a surplus of one of them. There are a small group of elements which decline to form chemical bonds - these are known as the noble elements. (Helium, Neon, Argon etc. What kind of bond holds the atoms of a single water molecule together? Each atom has eight protons, eight electrons and eight neutrons. The inner ring has two electrons, while the outer ring has six. The maximum an electron ring can hold is eight, though the first ring can hold only two. Energy storage: starch (plants) & glycogen (animals, humans). Structural support: cellulose (plant cells) & chitin (arthropod exoskeletons & fungi cell walls). Lipids. Are hydrophobic, aren't polymers, and made up of monomers, such as waxes, oils, fats, and steroids. Serve as an important energy source and insulation and are made up of fatty acids and glycerol. Everything is made of atoms. An atom is the smallest particle of an element, like oxygen or hydrogen. Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That's why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules. How is water made? Water is formed when oxygen and hydrogen atoms combine, and it takes a total of three atoms to make a water molecule. Two of the atoms are hydrogen and the last atom is oxygen, hence the chemical formula H2O. Full Answer >. The covalent bonds between hydrogen and oxygen in a molecule of water are the most polar. Water is a covalent molecule, meaning the two atoms of hydrogen and the one atom of oxygen share electrons. What is the structure of carbohydrates and its chemical formula? Both simple sugars (glucose, fructose,galactose, etc.) & polymers such as starch made from these and other subunits. Exist in a ratio of 1 carbon: 2 hydrogen: 1 oxygen or CH2O.
A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.
