C can be the only correct answer - 6.023 x 10^23 is the amount of molecules in a mol of an element. 4.5 x 6.023 x 10^23 can not equal anything but C.
4.5 x 6.023 x 10^23 = 2.71035 x 10^24

Explanation:
Answer:
Ti
Explanation:
Ti is titanium and does not share any similar properties with the likes of Si, silicon and At, astatine.
- Titanium is a transition metal and a solid.
- Silicon and Astatine are non - metals.
- Silicon and Astatine also belongs to the p-block on the periodic table whereas Titanium is found on the d-block.
- Silicon and Astatine would prefer to take part in reactions where they can gain electrons because they are non metals whereas Titanium due to its metallic property would prefer a reaction where it can lose electrons.
For such calculation, we apply Planck's equation:
E = nhc / λ; where n is the number of photons, h is the Planck's constant, c is the speed of light and λ is the wavelength of the light.
As is visible from the equation, energy and wavelength have an inverse relationship. Therefore, larger energy drops produce smaller wavelengths and smaller drops produce larger wavelengths.
