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...

It readily loses its electron to form a positive ion like other alkali metals. ..
It readily loses its electron to form a positive ion like other alkali metals. ..Crystalline character
In ionic-compounds each ion is surrounded by oppositely charged ions uniformly distributed all around the ion,thus resulting in a three dimensional solid aggregate called an ionic crysta..
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..

Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
I have experienced very innovative way of learning, I joined online tutoring at Tutorvista few months back when I was in grade 10, I scored really well in grade 10 and ny parents were really happy.
