Formulas for Compounds The formula of a well-known compound, water, is H2O. Water is made up of molecules, and the formula shows that each molecule consists of two atoms of hydrogen, H, bonded to an atom of oxygen, O. The subscript 2 indicates that there are two atoms of hydrogen in...
The Balmer formula for the spectrum of atomic hydrogen is shown to be analogous to that in Compton effect and is written in terms of the difference between the absorbed and emitted wavelengths. The g-factors come into play when the atom is subjected to disturbances (like changes in the ...

When cells are deprived of oxygen, they can neither function nor survive. This is called chemical suffocation, and it is fatal.Cyanide Definition Cyanide is a molecule that consists of one carbon atom triple-bonded to one nitrogen atom. The chemical formula for cyanide is CN–. It is most ...
This atom is composed of two copper ions and one oxygen ion. The oxygen's formal charge is -2, and copper's formal charge is +1. The copper ion with a +1 formal charge is called cuprous ion Cu+1. Cu2O's chemical name is cupric oxide or copper(I) oxide.What...

While factor of the radius is then lost into the mathematial expression, it remains of physical significance: as the ballet dancer pulls in her arms, the radius of rotation decreases, and the speed of rotation increases. Angular momentum itself has a vector, given by the "right hand rule,"...
This creates a smaller atomic radius, higher ionization energy, and higher net positive charge on the atom. How do you find the effective nuclear charge of an atom? To find the effective nuclear charge of an atom, use the formula, Zeff = Z - S, where Z is the atomic number and S ...
