Theorem 3 (S.S.S.) Similarity - If three pairs of corresponding sides are proportional then the two triangles are similar. In D ABC and D PQR, D ABC ~ D PQR The above three theorems are without proof. Such theorems can be called postulates. Now, let us compare similar triangles and congru..

If three pairs of corresponding sides are proportional then the two triangles are similar. In D ABC and D PQR, D ABC ~ D PQR The above three theorems are without proof. Such theorems can be called postulates. Now, let us compare similar triangles and congruent triangles: In PQ || BC, AP = 7.2 cm, A..

If a pair of corresponding angles are equal and the sides including them are proportional, then the triangles are simila..

The orbital angular momentum of a 's' orbital is zero, as 'l' = 0. This means that the probability of finding an electron at a particular distance from the nucleus is the same in all directions/at all angles. Since the distribution of electron density is symmetrical, the shape representi..

s orbitals are non-directional and spherically symmetrical, This means that the probability of finding the electron is same in all directions at a particular distance from the nucleus, The 1s orbital is shown in the figure 1.3. fig 1.3 - Shapes of 1s and 2s o..

's' block elements, (except helium) are those in which the valence-shell is the 'ns' orbital and where the last electron enters into the 's' orbital of the outer element. The general outer electronic configuration of such elements is either ns 1 or ns 2 . The 's' bloc..

N 1 and S N 2 mechanisms The reaction mechanism of S N 1 or S N 2 substitutions depends upon a number of factors as follow..

Solar Constant (S) - The solar constant is defined as the amount of heat energy received per second per unit area by a perfect black body placed at the surface of the Earth with its surface being held perpendicular to the direction of the sun's rays. The value of solar constant is 1388 Wm..

It is observed that the electron is not only revolving around the nucleus but it is also spinning on its own axis. The spin of the electron produces a small magnetic field as a result of which the electron behaves as a 'tiny magnet'. This quantum number describes the spin orientation of the e..
