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..

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..

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..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
