Answer:
The s-block of the periodic table has 1 orbital
we know that each orbital consists of 2 electrons
and since the periodic table arranges the elements on the basis of their atomic number,
the s-block spans 2 groups.
This is also the reason why the p-block spans 6 groups, d-block spans 10 groups and f-block spans 14 groups

Answer:
The energy of the photon is 1.718×10−26J.
Explanation:
The energy of the photon is
1.718 × 10 − 26J. You use the formula E =, where h is Planck's Constant,c is the speed of light, and λ is the wavelength of the photon.
E== = 1.718×10−26J.
