Answer:
The great jump in ionization energy indicates that the most stable form of the sodium atom- the noble gas configuration, was reached after the removal of the first electron.
Explanation:
Sodium atom has an electronic configuration of 2,8,1. After the first electron has been removed from a sodium atom, the ion formed now has a noble gas configuration which assigns stability to it.
Noble gases have very high ionization energy due to the stability conferred on the by virtue of their completely filled outermost shells. They do not have need to lose electrons to attain stability. Also, because they have the most protons of their period, their atomic radius is reduced as electrons are pulled into the nucleus.
So, the great jump in ionization energy indicates that the most stable form of the sodium atom- the noble gas configuration, was reached after the removal of the first electron.
Sulfur hexafluoride, composed of six fluoride atoms and one sulfur atom. It is used as gas under pressure as an insulator in gas insulated switchgear (GIS). It is not dangerous and does not pose any toxic hazard.
Answer:
B. pour the reagent into a small beaker before using it
Explanation:
Let's explore all the mentioned practice
A. Leftover reagents should not be discarded in the sink but discarded according to the disposal method present in the safety data sheet (SDS) of the chemical.
B. Reagents should be poured in a clean beaker for use to avoid contamination in the original reagent bottle
C. This is not a good practice, as the plastic pipet tends to contain some impurity in its tip.
D. This is also a bad practice. Firstly, a reagent should be taken according to the need. If there is leftover, it should be discarded as it most probably contains contamination in it
