what is the modern purpose of this reaction?
The number of unpaired electrons in a chromic ion Cr 3+ (atomic number = 24) is: (1) 6 (2) 4 (3) 3 (4) 1 Ans: 3
what is the principal of radiometric titration
Atoms consists of protons, neutrons and electrons. If the mass of neutrons and electrons were made half and two times respectively to their actual masses, then the atomic mass of
Cu 2+ will have the following electronic configuration: (1) 1s 2 , 2s 2 , 2p 6 , 3s 2 , 3p 6 , 3d 10 , (2) 1s 2 , 2s 2 , 2p 6 , 3s 2 , 3p 9 , 4s 1 (3) 1s 2 , 2s 2 ,
whAT IS SOLID STATE
