<span>Which
of the following best describes the electron cloud model?
THE ELECTRON CLOUD MODEL WAS DEVELOPED BY SCHRODINGER. IT STATES THE THE ELECTRONS ARE NOT PARTICLES MOVING AROUND THE NUCLEUS IN FIXED ORBITY BUT THEIR LOCATIONS CAN ONLY BE STATED BY A PROBABILITY DENSITY IN FORM OF CLOUD AROUND THE NUCLEUS.
THEN THE MAIN POINT OF THE CLOUD MODEL IS THAT THE ELECTRONS ARE NOT IN FIXED ORBITS AROUND THE NUCLEUS BUT THEIR LOCATION IS STATED BY A PROBABILITY FUNCTION THAT IS LIKE A CLOUD REGION.
A. It shows
that electrons usually carry a negative charge.
FALSE: ELECTRONS ALWAYS CARRY NEGATIVE CHARGE
B. It shows that
electrons remain in high-energy subshells.
FALSE: ELECTRONS OCCUPY THE LOWEST-ENERGY SUBSHELLS AVAILABLE UNLESS THEY ARE EXCITED (ABSORB ENERGY)
C. It shows that electrons
move quickly in circular orbits.
FALSE: ELECTRONS DO NOT MOVE IN CIRCULAR ORBITS.
D. It shows that the electrons within
an atom do not have sharp boundaries.
TRUE. THE IDEA OF A CLOUD IS A DIFFUSSE REGION WHERE IS A 90% OF PROBABILITIES TO FIND THE ELECTRON, AND THEY DO NOT HAVE SHARP BOUNDARIES.

Answer:- 
Solution:- Wavelength is given and we are asked to calculate the frequency. The equation that correlates frequency with wavelength is:
where, 
is the symbol for frequency, c is the symbol for speed of light and 
is the symbol for wavelength.
Speed of light is 
and the wavelength is given as 
.
Let's plug in the values in the equation and so the calculations to calculate the frequency:
(since, 
)
So, the frequency of the wave is .
When scientists conduct an experiment and analyze the results, the next step is to write up a report that describes the experiment and the results and submit it for publication in a scientific or medical journal that is “peer reviewed.”
It’s a molecule hope this helps
If one were to match the ratio of atoms of the elements found in this molecular formula of artificial sweetener it would be :
Carbon - 7 atoms
Hydrogen - 5 atoms
Nitrogen - 1 atom
Oxygen - 3 atoms.
