Why are protons in an atom so important? question 8 options: there are more protons than electrons or neutrons in a neutral atom. protons determine the atoms' identity (type of element) and where it is located on the periodic table. protons determine an atom's chemical properties and how it will react with other elements. protons are bigger than all the other particles in an atom.

The answer is the second option "Protons determine the atom's identity (type of element) and where it is located on the periodic table." Protons determine the element if the number of protons kept changing then the element would keep changing and there would be no use for the periodic table. Electrons have the same amount of protons and neutrons are determined by subtracting the atomic mass to the atomic number.

Hope this helps!

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
