Answer:
What do you mean by this question, did you mean Coke, or what did you mean because I do not understand.
Explanation:
Metals are placed in one spot,the nonmetals are placed in another spot,And lastly the metalloids are seperated
The total pressure in the container after the three gases are mixed is 6 atm and the partial pressure of He is 1 atm.
<h3>What is Dalton's Law of Partial Pressure ?</h3>
According to Dalton's Law of Partial Pressure , the pressure exerted by a mixture of gas is equal to the sum of the partial pressure of the gases in the mixture.
P(total) = p₁ +p₂+p₃+.....
As the volume of the containers are same and the
n = 1*5/RT for Helium
n = 2*5 /RT for Neon
n= 3*5/RT for Argon
Mole fraction = moles of the element/Total moles
Moles fraction of Helium is
= 1/6
Total Pressure in the container = 1 + 2 +3 = 6 atm
The partial pressure of Helium will be
=Mole fraction * Total pressure
=(1/6)*6 atm
= 1 atm , as the volume is same the temperature is same , the pressure will also be same.

Answer:
Transition Element
Explanation:
Transition elements are defined as those elements which can form at least one stable ion and has partially filled d-orbitals. They are also characterized by forming complex compounds and having different oxidation states for a single metal element.
Transition metals are present between the metals and the non metals in the periodic table occupying groups from 3 to 12. There general electronic configuration is as follow,
(n-1)d
¹⁻¹⁰ns
¹⁻²
The general configuration shows that for a given metal, the d sublevel will be in lower energy level as compared to corresponding s sublevel. For example,
Scandium is present in fourth period hence, its s sublevel is present in 4rth energy level so its d sublevel will be present in 3rd energy level respectively.
Hence, we can conclude that for transition metals the electron are present in highest occupied s sublevel and a nearby d sublevel
