Green plants absorb sunlight to power photosynthesis, the chemical synthesis of food from water and carbon dioxide. The compound
Kamila [148]

Answer:

698 \ THz

Explanation:

Data provided as per the question below:-

Wavelength = 430.nm

The computation of the frequency of the light is shown below:-

Frequency = Velocity of light ÷ Wavelength

The  Velocity of light = = {3.0 \times 10^8 \ m/s}

Wavelength = 430 nm = 4.30 \times 10^-^7 m

Frequency = \frac{3.0 \times 10^8 \ m/s}{4.30 \times 10^-^7}

= 6.98 \times 10^1^4 \ hz

= 6.98 \times 10^2 \ Thz

= 698 \ THz

Therefore for determining the frequency we simply applied the above formula.

What is the last energy level of N? Mg?
Alexandra [31]

Answer:

2

3

Explanation:

To infer the last energy of the given atoms, we need to write their electronic configuration:

For N = 1S² 2S² 2P³

     Mg  = 1S² 2S² 2P⁶ 3S²  

The energy levels are usually designated as;

   n = 1

   n = 2

   n = 3

   n =4

For N, the last energy level is 2

     Mg, the last energy level is 3

We can also determine this number by the periods the atoms can be found.
