The frequency of the green light of the electromagnetic spectrum is 5.45 × 10¹⁴ Hz.
The green light is found in the visible region of the electromagnetic spectrum.
An Electromagnetic is a spectrum which is made up of all kind of wave is constitute and electric as well as magnetic field.
The green light which is the constituent of the white light fall under the visible region of the electromagnetic spectrum so it can have the frequency 5.45 × 10¹⁴ Hz.
This frequency is more than the infrared frequency but less than the ultraviolet frequency.

Answer:
12 (Magnesium- Mg)
Explanation:
Looking at the four numbers, we have:
Magnesium, Silicon, Sulfur, and Chlorine.
We can eliminate two of the answers immediately just by looking at the periodic table.
Sulfur and Chlorine are on the nonmetal side of the periodic table. So that's <em>definitely</em> not it. That leaves Magnesium and Silicon.
Silicon is a Metalloid. Magnesium is an Alkaline earth Metal.
Metaloids are elements that have a mix of both<em> metal</em> and<em> nonmetal </em>properties (luster, how it feels, etc.). Since it's a MIX and Magnesium is just straight METAL-
We can say Magnesium has the most metallic properties.
hope this helps!!
An atom is the smallest unit of an element
Using newton's second law, F = ma, the answer is -2.5 m/s^2.
