The method is based on the common assumption that the stopping power is a linear decreasing function of the energy, in the energy range of interest in RBS, that is from 1.4 MeV to 2.0 MeV. The total yield can then be integrated analytically, and the number of atoms in the film can be...
Analyze the chemical formula and write down the element types that comprise the compound as well as the number of atoms of each type. The first example, KNO3, contains the elements potassium (K—1 atom), nitrogen (N—1 atom) and oxygen (O—3 atoms). The second example, SO42-, contain...
in chemistry, the oxidation number helps to keep track of the electrons in an atom. it is a number, which is generally assigned to the atoms of the chemical substance. the oxidation number can be positive, negative or it can be zero. it indicates that electrons lose or gain in the atom...

Avogadro's constant units may be difficult to deduce at first glance. How can such a strange concept have a unit? Let's have a look at the equation this Avogadro's number calculator uses: number of atoms = Avogadro's number × moles Now, by knowing the units of the other two variables...
is radioactive and used for carbon dating. atomic carbon is short-lived but it is stabilised by allotropic forms. carbon has three allotropes namely diamond, graphite and amorphous form. the properties of these allotropes are different due to the different arrangements of c atoms inside them....
1 Counting atoms: Avogadro's number Owing to their tiny size, atoms and molecules cannot be counted by direct observation. But much as we do when "counting" beans in a jar, we can estimate the number of particles in a sample of an element or compound if we have some idea of the ...
