Answer: beta, gamma, alpha
Explanation: Beta is weakest gamma is middle alpha is strongest
Answer : The energy released by an electron in a mercury atom to produce a photon of this light must be, 
Explanation : Given,
Wavelength = 
conversion used : 
Formula used :
As, 
So, 
where,
= frequency
h = Planck's constant = 
= wavelength = 
c = speed of light = 
Now put all the given values in the above formula, we get:
Therefore, the energy released by an electron in a mercury atom to produce a photon of this light must be,
Heyo, I believe that the answer would be D. The valence electrons are given up by the K and gained by the F.
The trend in electronegativity values across period 3 from sodium to chlorine is that sodium with 11 protons is the least electromagnetic element and chlorine with 17 protons is the most electronegative element.
<h3>What is electronegativity?</h3>
It should be noted that electronegativity simply means a chemical property that describes the tendency of an atom to attract elements towards it.
In this case, the trend in electronegativity values across period 3 from sodium to chlorine is that sodium with 11 protons us the least electromagnetic element and chlorine with 17 protons is the most electronegative element.

Answer
In a true decomposition reaction, the addition of energy in the form of heat or electricity is often required.
Explanation
A decomposition reaction is a chemical reaction that starts with single reactants to give new compounds as the products. These reaction requires a source of energy that could be light, heat or electricity to facilitate the breaking-down of the chemical bonds.
