A green leaf has a surface area of 2.50 cm2. If solar radiation is 1000 W/m2, how many photons strike the leaf every second? Assume three significant figures and an average wavelength of 504 nm for solar radiation.
Solution Step 1 (a)As we move down the noble gas family the size of the atoms increases. Xenon is found towards the bottom and has a much larger size than fluorine. Thus in Xenon, the valence electrons are away and loosely bound to the nucleus. So they react with other elements forming compounds.
