Here we have to compare the Bohr atomic model with electron cloud model.
In the Bohr's atomic model the electrons of an element is assumed to be particle in nature. Which was unable to explain the deBroglie' hypothesis or the uncertainty principle and has certain demerits.
The uncertainty principle reveals the wave nature of the electrons or electron clod model. The Bohr condition of a stable orbits of the electron can nicely be explained by the electron cloud model, the mathematical form of which is λ = nh/mv, where, λ = wavelength, n is the integral number, h = Planck's constant, m = mass of the electron and v = velocity of the electron.
The integral number i.e. n is similar to the mathematical form of Bohr's atomic model, which is mvr = nh/2π. (r = radius of the orbit).
Thus, the electron cloud model is an extension of the Bohr atomic model, which can explain the demerits of the Bohr model. Later it is revealed that the electron have both particle and wave nature. Which is only can explain all the features of the electrons around a nucleus of an element.
The percent composition of the compound is 79.87 % of carbon and 20.12% of hydrogen
Explanation:
Given:
mass of carbon = 13.18 grams
mass of hydrogen = 3.32 grams
percent composition of compound =?
From the given data total mass of the compound is calculated
13.8 + 3.32
= 16.5 grams
The individual percentage of hydrogen and carbon will be calculated as:
percent composition = 
x 100
For carbon,
x 100
percent composition of carbon = 79.87 % of carbon.
for hydrogen:
= 20.12 % of hydrogen
In the compound given 79.87 % of carbon and 20.12% of hydrogen is present.
The correct way to write this number in scientific notation : 6.022 x 10²³
<h3>Further explanation
</h3>
Scientific Notation is a standard form of writing numbers used in mathematical operations
The rules:
1. Writing order : first digit, decimal point, next digit
2. Then followed by powers of 10 (the value can be +/-)
If the value is> 10 (the power of 10 is +), the decimal point is moved to the left, to the right of the first digit
If the value is <10 ((the power of 10 is -), the decimal point is moved to the right, to the right of the first digit
I certainly didn't count the details of the number of zeros listed, but only saw the answer choices.
And the right ones are: 6.022 x 10²³
The answer to your question is liquid hydrogen
Answer: The nonliving parts of an ecosystem are called abiotic factors. Abiotic factors include water, sunlight, oxygen, temperature, and soil.
