The Lewis structure depicts the number valence electrons surrounding an atom. These are the electrons present in the outer shells which can participate in bonding with another atom or remain as non-bonding (lone pair) electrons.
In the given example there are 7 dots or 7 electrons surrounding a Cl atom. This corresponds to 7 valence electrons with a configuration that can be given as: s²p⁵ and specifically, 2s²2p⁵
<u>Answer:</u> The frequency of the light is
<u>Explanation:</u>
The equation used to calculate the energy for a transition, we use the equation:
where,
n = principal energy level
Calculating the energy difference:
To calculate the energy of the light for a given frequency, we use the equation given by Planck, which is:
where,
E = energy of the light =
h = Planck's constant =
= frequency of the light = ?
Putting values in above equation, we get:
Hence, the frequency of the light is
Answer: 24.0g of NaCl.
The number seems the highest, but I am not in Honors Chem (I am taking honors biology), so I do not know.
