ground state transition

Transition State Theory - According to this theory, the reactant molecules must come together to form an arrangement of atoms/molecules that facilitates the formation of products. This arrangement of the reacting species is called the transition state. A simp..

The first row transition elements show variable oxidation states. Zn is an exception among them. As it has fully filled d-orbital, it exhibits only +2 oxidation state. The oxidation states of first row transition metals are shown belo..

All the elements of this group have ns 2 np 4 configuration in their outermost shell. Therefore, the atoms of these elements try to gain or share two electrons to achieve noble gas configuration. Since oxygen has a very high value of electronegativity, it tends to achieve noble gas configuration pr..

In 1967, the atomic clock was adopted, choosing caesium-133 atom, which emits electromagnetic radiation of a precise and unvarying frequency, corresponding to the transition between two hyperfine levels of the ground state..

>Unit of Mass is defined as "the mass of a particular solid cylinder made of platinum-iridium alloy kept in Paris, known as the International Prototype Kilogram". Unit of time, second, is equal to the duration of 9192631770 periods of the radiation corresponding to the transition between ..

Gamma decay is the phenomenon of emission of gamma ray photon from a radioactive nucleus...

In the first row transition elements the ionic radii decreases with increase in atomic number. The value of ionic radii also depends on the oxidation state of metals. As the oxidation state increases the ionic radii decreases and as the oxidation state decre..

The structures of different molecules can be explained on the basis of hybridization. For e.g., in case of carbon, the ground state electronic ..
