Question

The molecular formula for ozone is ______
(a) O
(b) ${ O }_{ 2 }$
(c) ${ O }_{ 3 }$
(d) ${ O }_{ 4 }$

Answer 1

Hint: Inside the Earth's stratosphere is made by U.V striking conventional oxygen molecules containing two oxygen atoms (${ O }_{ 2 }$), parting them into singular oxygen atoms (atomic oxygen); the atomic oxygen then combines with unbroken ${ O }_{ 2 }$ to make it.

Complete answer:
The formula for ozone is ${ O }_{ 3 }$ as ozone contains three atoms of oxygen. Nascent oxygen O and tetra atomic oxygen ${ O }_{ 4 }$ does not exist in the atmosphere, whereas ${ O }_{ 2 }$
is the atmospheric oxygen that we breathe in.

Additional information: The ozonosphere or ozone shield might be an area of Earth's stratosphere that ingests the majority of the Sun's U.V. It contains a high convergence of ozone ( ${ O }_{ 3 }$) regarding different pieces of the air, albeit still little concerning different gases in the stratosphere. The standard ozone center in Earth's atmosphere, all in all, is about 0.3 parts per million while the ozone contains 10 segments for every million ozone. The ozonosphere is particularly found inside the lower bit of the stratosphere, from roughly 15 to 35 kilometers (9.3 to 21.7 mi) above Earth, in spite of the fact that its thickness changes seasonally and geographically.
So the correct answer to the above question is ‘(c) ${ O }_{ 3 }$’.

Note: The ozonosphere ingests $97\% - 99\%$ of the Sun's medium-recurrence U.V (from around 200 nm to 315 nm frequency), which in any case would possibly harm uncovered living things close to the surface.
UV radiation fit for entering nitrogen is part into three classes, upheld by its wavelength; these are referenced as UV-A (400–315 nm), UV-B (315–280 nm), and UV-C (280–100 nm).
