Row Matrix
A matrix having only one row is called a row-matrix. For example: A[1 3 2 -2] is a row matrix of order 1 x..
First Row Elements
Electronic Configurations of Atoms - Based upon the rules and sequence of energy levels, one can write the electronic configurations of atoms of some rows of the periodic tabl..
Third Row Elements
The third row elements are from sodium to argon. The build up of these eight elements proceeds exactly in the same manner as discussed above. Here 3s- and 3p-orbitals are filled in place of 2s- and 2p-orbitals as has been done in case of Li to N..

Cindy went for a flower show. Roses were arranged such that there were 8 in the first row, 12 in the second row, and 16 in the third row. How many could be there in the fourth row? => 22 or 20 or 18 or 24..
Second Row Elements
In lithium (Z =3), the third electron goes to the next 2s orbital. In Beryllium (Z = 4), the fourth electron fills 2s orbital and in boron (Z = 5), the next electron goes to the next available 2p orbital. In carbon, the sixth electron is also to go into the 2p orbital as 2p subshell can accommodate..

In potassium (Z=19) and calcium (Z=20), electrons enter the 4s-orbitals in accordance with the fact that 4s-orbital is slightly lower in energy than 3d-orbital. With scandium (Z=21), 3d-subshell comes into use and from scandium to zinc, this subshell is gradually filled up. The electronic configura..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
This was excellent. I was cluesless on this subject and now I completely understand it.Mind blowing service,Thank you Tutor Vista
