Answer 1

Answer:

3) As you go down the periodic group, the size of the atom of the element increases, which then increases the force of attraction between the electrons and the nucleus. This decreases the reactivity of the element.

4) As the frequency decreases, the wavelength increases.

So, the order is:

10^11 < 0.9 * 10^11 < 4.2 * 10^8 < 8.8 * 10^3
