The wavelength is 4.0 * 10^-13 m while the frequency is 7.5 * 10^20 s−1
Using the formula;
E =hf
Where
E = Energy of the photon
f = Frequency of photon
h = Plank's constant = 6.6 * 10^-34 Js
To obtain the energy in Joules;
E = 3.02 × 10^11 J/mol/6.02 * 10^23 mol
= 5 * 10^-13 J
f = E/h
f = 5 * 10^-13 J/6.6 * 10^-34 Js
f = 7.5 * 10^20 s−1
f = c/λ
c = speed of light = 3 * 10^8 m/s
λ = c/f
λ = 3 * 10^8 m/s/7.5 * 10^20 s−1
λ = 4.0 * 10^-13 m
The wavelength is 4.0 * 10^-13 m while the frequency is 7.5 * 10^20 s−1

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

Answer:
Chlorine can be found in Period 3.
Explanation:
Periods on the periodic table are the rows (horizontal sections) that group elements together. By looking across Period 3, you will find Cl (chlorine).
