7 valance electrons the Lewis structure for a chlorine atom show.

<u>Explanation:</u>

Lewis structure is used to keep track of the valance electrons of each atom and share them in bonding. Every valance electron is represented as a dot around the element to keep their count.

Paired VE’s are shown as ‘:’ and unpaired as ‘.’ in the representation. A chlorine Cl atom has 17 electrons. & of them are valance electrons. Out of the seven six are paired electrons and one is unpaired.

Answer: D

Explanation:

Chlorine is in group 7 or (VII) in Roman numerals, which means it has 7 balance electrons. It only needs one electron to become stable, hence it is next to the noble gases

Vesnalui [34]

Answer: The maximum wavelength of light for which a carbon-chlorine Single bond could be broken by absorbing a single photon is 354 nm

Explanation:

The relation between energy and wavelength of light is given by Planck's equation, which is:

$E=\frac{Nhc}{\lambda}$

where,

E = energy of the light = $338kJ=338000J$ (1kJ=1000J)

N= avogadro's number

h = Planck's constant

c = speed of light

$\lambda$ = wavelength of light

$338\times 1000J=\frac{6.023\times 10^{23}\times 6.6\times 10^{-34}\times 3\times 10^{8}}{\lambda}$

${\lambda}=0.354\times 10^{-6}m=354nm$ $(1nm=10^{-9}m$

Thus the maximum wavelength is 354 nm
