The two elements that make up a molecule of water are hydrogen and oxygen; there are two hydrogen atoms and one oxygen atom, resulting in the chemical formula H2O. Hydrogen and oxygen bond together due to the number of electrons in their orbitals.Know More
An oxygen atom has six electrons in its second shell, and a hydrogen atom has one electron in its first shell. A second shell is considered to be full at eight electrons, while a first shell is full at two electrons.
The oxygen atom bonds to the two hydrogen atoms through the use of covalent bonds, which allow the atoms to share their electrons. The oxygen atom has a full second shell, and the two hydrogen atoms have full first shells.Learn more about Atoms & Molecules
Water was not invented, but is a naturally occurring chemical compound consisting of two hydrogen atoms covalently bonded with one oxygen atom. Approximately 71 percent of the earth's surface is covered by water.Full Answer >
Water is a compound made up of one oxygen atom and two hydrogen atoms. The electrons are shared between the oxygen and hydrogen atoms. However, the electrons spend more time on the oxygen section of the molecule.Full Answer >
The oxygen atom in a water molecule carries a partial negative charge, and the two hydrogen atoms carry a partial positive charge. Oxygen is more electronegative than hydrogen, so in a water molecule, the bonding electrons are not shared evenly.Full Answer >
The chemical formula for hydrogen gas is H2. Its molar mass is 2.016 grams per mole, and it exists as a gas at standard temperature and pressure, where its density is 0.09 grams per liter. Hydrogen's melting point is -434.49 degrees Fahrenheit and its boiling point is -423.182 degrees Fahrenheit.Full Answer >
