An element X with the electronic configuration 1s 2 , 2s 2 , 2p 6 , 3s 2 , would be expected to form the chloride with the formula: (1) XCl 3 (2) Xcl 2 (3) XCl
Q. Example of octahedral complexes? Let us now turn our attention to the complexes having transition metal ion with d 2 or d 3 electrons. With these configurations, there are
The nucleus of the element 21E^45 contains

Q. What is Percent error? Quantities measured throughout an experiment are called experimental values. The dissimilarity between an accepted value and an experimental value is
why ionisation energy of aluminium is greater then Ga?
Experimental evidence for the existence of the atomic nucleus comes from: (1) Millikan's oil drop experiment (2) Atomic emission spectroscopy (3) The magnetic bending of
1 gm of a metallic oxide on reduction gives 0.68 gm of the metal. ans) Mass of metal/mass of oxygen=eq. mass of metal/eq. mass of oxygen. applying this we get .68/.32=x/8 x=1
Q. Estimation of synthetic food colours in foods? Food colours in various products need to be isolated, identified and then quantitatively measured for their limits. Estimatio
