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
.
If an element contains 8 electrons, then there would be 6 electrons that will be placed in the 2nd valence shell. Each shell in an atom can only take up a fixed number of electrons. For the first shell, only two electrons can be found. For the second shell, it can hold up to 8 electrons. However, for this case only six electrons can be found since the others are found in the first shell.
Answer:The the 
for the given reaction is 179.98 J/K.
Explanation:
The the for the given reaction is 179.98 J/K.
Explanation:
There will occur a straight line for the curve of Ln[(CH_{3})_{3}CCl] Vs. time. Since, it is a first order reaction therefore, the formula of its half-life will be as follows.
Half-life = 
or, k = 
= 
So, rate of the reaction will be as follows.
Rate = ![[(CH_{3})_{3}CCl]^{1}](https://tex.z-dn.net/?f=%5B%28CH_%7B3%7D%29_%7B3%7DCCl%5D%5E%7B1%7D)
= 
= 0.000473 
= 
Thus, we can conclude that the instantaneous rate of given reaction is .
