Sketching
If, on occasion, you are stuck for words, try drawing or sketching or even cartooning the pictures in your mind. This is especially useful if you are a visual learner - that is, you respond better to pictorial representations of material than to written descriptions or explanation..
Electropositive character
Hydrogen like alkali metals is electropositive because both can lose one electron readily as..
Hydrogen like alkali metals is electropositive because both can lose one electron readily as..Reducing character
The reducing character of the hydrides of group 15 elements increases from NH 3 to BiH 3 . Thus, increasing order of reducing character is as follows: NH 3 < PH 3 < AsH 3 < SbH 3 < BiH 3 Explanation: The reducing character depends upon the stability of..
Metallic character
The elements of group 15 are less metallic. However on going down the group, the metallic character increases from N to Bi. For e.g.,, N and P are non-metallic, As and Sb are partly non-metallic while Bi is a metal...

Most of the transition elements of the first row form metallic bonds due to the presence of incomplete outermost energy level. So, all the transition elements exhibit metallic characters. The strength of the metallic bond depends upon the number of unpaired d-electrons. As the number inc..
Reducing character
Carbon monoxide is a reducing agent. It reduces many oxides to the respective metal. For example, CO also reduces I 2 O 5 to iodine...
Neutral character
Oxygen is neither acidic nor basic. Both blue and red litmus are unaffected by oxyge..
Magnetic Character
If all the electrons in the molecule of a substance are paired, the substance is diamagnetic. On the other hand, if there are unpaired electrons in the molecule, the substance is paramagnetic. Magnetic moment can be calculated as follow..
Curve Sketching
Curve Sketching - The graph of a given function gives a visual presentation of the behaviour of the function involving a study of symmetry, rise and fall, region of existence, passage through specific points etc. The following points are helpful to trace the curv..
