It’s D. Rutherford discovered the atomic nucleus.
Silicon dioxide is SiO2. Silicon has 4 valence electrons, while each oxygen has 6 valence electrons. This can be shown as
** * *
** O * * Si * * O **
* * **
At points where there is one valence electron, represented by a lone *, the electrons will be 'shared' between the atoms. This will make silicon dioxide appear as
** *--------------- *
** O *--* Si * ------ * O **
*------- * **
, as the lines with no arrows indicate that each electron moves between the atoms, and does not stay with one forever.
Explanation:
On comparing blue visible light with red visible light, there is difference in the wavelength, frequency, and energy. The difference between both red and blue visible lights are as follows.
Blue visible light:
- It has low wavelength.
- High frequency.
- More energy.
Red visible light:
- It has high wavelength.
- Low frequency.
- Less energy.
