Answer: The frequency of this light is 
.
Explanation:-
To calculate the frequency of light, we use the equation:
where,
= wavelength of the light =
c = speed of light = 
= frequency of light = ?
The frequency of this light is .
Atoum is the process of how large molecules are formed
Answer:
False
Explanation:
Compounds are chemically combined
lemonade is not
If the squeezed lemonade is made by squeezing lemons to extract the juice and mixing it with water and sugar, it would be a homogenous mixture.
If it contains a pulp than it would be heterogeneous
The position of a given element in the periodic table depends on the atomic number. Further the atomic number is equal to the number of protons and the number of electrons of the particular element.
Also for the considered element, depending on the atomic number, the placement in the periodic table will create groups (columns) and periods (rows).
As a example we will take two atoms carbon (C) and nitrogen (N):
carbon (C) - has a atomic number of 6, it contains 6 protons and 6 electrons, and you find this element in the group 14 and period 2 in the periodic table
nitrogen (N) - has a atomic number of 7, it contains 7 protons and 7 electrons, and you find this element in the group 15 and period 2 in the periodic table
Noble Gases is the answer. These elements have a full outer shell composed of eight valence electrons, meaning that they do not need to gain electrons from other elements in reactions, making them nonreactive (inert).
