The electronic configuration of copper (29 cu) is: (1)1s 2 , 2s 2 , 2p 6 , 3s 2 , 3p 6 , 3d 9 , 4s 2 (2) 1s 2 , 2s 2 , 2p 6, 3s 2 , 3p 6 , 3d 10 , 4s 1 (3) 1s 2 , 2s
The total number of unpaired electrons in d- orbital's of atoms of element of atomic number 29 is: (1) 10 (2) 1 (3) 0 (4)5 Ans: 0
ELECTROCHEMICAL THERMODYNAMICS Notation: To avoid repetitive drawing of complicated cells diagram, a common notation has been adopted for cells. All electrical contacts
Q. What are the physical properties of solids? Ans. Most solids eventually melt when heated. This is because the particles gain enough energy to exceed the attractive for
