-20F is colder than -20C. This is because the Fahrenheit scale has a smaller degree interval than the Celsius scale, so -20F is a lower temperature than -20C.
It is about 20F and -7C.
20F
It is about 20F and -7C.
527 = 20f
20f
I think its about 20F to about 60F.
-20F to +100F
20F, I think this means that it is an isomer of F with an atomic mass of 20. Based Flourine has an atomic mass of 18. So taking this into account the isomer should have the same number of protons but different number of neutrons. 20-9= 11. 20F has 11 neutrons
There are 9 protons in one atom of 20F, as fluorine has an atomic number of 9.
