state transition matrices

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..

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..

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..

'd' block elements have valence electrons in both their outermost and penultimate shells. Valence electrons belonging to the outermost shell or both shells may take part in a chemical reaction. Accordingly, more than one oxidation state can be shown by the same element; this is termed a..

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. One second (SI unit time) is defined as 9, 192, 631, 7..

In the first row transition elements all the elements except Zn form colored ions. As these elements have incomplete d-orbital, some amount of energy is required to promote the electrons from lower energy level to higher energy level. This process exhibits radiations from which the compo..

) and is, therefore, a first order reaction. Rate = k [RX] The order of reactivity depends upon the stability of carbonium ion formed in the first step. Since the 3 carbonium ion is most stable, the ionization of tertiary alkyl halide is favored. The order of reactivity for S N 1 reaction is, terti..
