Answer:
The ground state electron configuration of ground state gaseous neutral tellurium is [Kr]. 4d10.
<span> purity of the substance is usually the main error (for example: water with impurities will have m.p. less than 273K or 0 degree celcius while it's b.p. will be greater than 373K or 100 degree celcius). </span>
<span>-> air/ room temperature (it takes longer to cook in mountains and shorter at beaches) </span>
<span>-> parallax error (error by determining the meniscus of the thermometer) </span>
<span>and many more..</span>
It is the attraction between two atoms resulting from a redistribution of their outer electrons. Atoms form chemical bonds in order to make their outer electron shells more stable. Some resist due to some being very big and electronegative
