Question

In a microwave oven, water absorbs microwave photons and coverts them to heat which raises its temperature Calculate how many photons of microwave radiation with lambda = 3.0 mm should be absorbed by 1.0 g of water in order to raise its temperature by 1 degree C. Assume h = 6.62 times 10^-34 J-s; specific heat of water = 4 18 J/g-degree C; C = 3.00 times 10^8 m/s. Write the complete ground state electron configuration for the element molybdenum. Mo. Write the condensed electron configuration of Mo.

Explanation / Answer

4 a Mo = 42 1s22s22p63s23p6 3d10 4s2 4p6 5s24d4

      Mo   = 42 = [Kr]4d45s2

half filled and full filled electron configuration elements are more stable

4b. Mo= 42   = 1s22s22p63s23p6 3d10 4s2 4p6 5s14d5

    Mo   = 42 = [Kr]4d55s1
