row definitions

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..

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..

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..

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 Ne. For e.g., ..

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..

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..

Let R i denotes the i t h row of the matrix A = [a i j ] then the elementary row operations on the matrix A are defined as: 3. R i g R i + kR j means multiply each element of j t h row by k and add it to the corresponding elements of i t h row..

There are 100 rows in a theatre. Each row has 25 chairs. Find the number of chairs in the theatre. => 2500 or 2200 or 2400 or 2300..
