<span>Compare Bromine and Krypton on the basis of their properties, attributes and periodic table facts. Compare elements on more than 90 properties. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses. These similarities and dissimilarities should be known while we study periodic table elements. You can study the detailed comparison between Bromine vs Krypton with most reliable information about their properties, attributes, facts, uses etc.</span>
Answer:
Ideal gas explains the property of gas that has no inter-molecular attractions irrespective of temperature and pressure.
<u>Explanation:</u>
- Ideal gases assumes that the gases would experience no inter-molecular attraction and collision with other gases.
- These gases are perfectly exhibiting elastic collision in nature.
- The particle of gases moves slowly at lower temperature and the gases would become close when they exhibit high pressure.
- The "closeness of the gas-particle" and "low-speed characteristics" are the important observations noted.
- The inter-molecular forces deviate the property of gases from ideal gas behavior.
<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.
