The electronic configuration of a dipositive metal M 2+ is 2, 8, 14 and its atomic weight is 56 a.m.u. The number of neutrons in its nuclei would be: (1) 30 (2)32
This of the following occurs when two hydrogen atoms bond with each others: (1) Potential energy is lowered (2) Kinetic energy is lowered (3) Electronic motion ceases
why the water is compound
#
Tritium is the isotope of: (1) Hydrogen (2) Oxygen (3) Carbon (4)Sulpher Ans: Hydrogen
