Question

Please help it is urgent!!!!

Please answer this in a complete paragraph, it is in course hero but I do not have it .

Here's the question :
Imagine you are given a mystery element. It is, however, a discovered and known element. You may perform a maximum of two observations or tests to determine its identity. Time and money is critical, so you need to prioritize your tests. If you can get by with a single test, you get 100 super-geek points from your research lab team. Pick your two tests, number them as #1 and #2, and justify why you think these two will certainly be enough (and why the first might well be enough all by itself.) The available tests are classification into metal, non-metal, or metalloid, count of valence electrons, count of electron shells, atomic radius (error range: +/- 1 pm), electronegativity (error range: +/- 0.1), first ionization energy (error range: +/- 10 kJ/mole), melting point (error range: +/- 10 C), and boiling point (error range: +/- 20 C).

Answer 1

Answer : To determine any unknown element given for analysis we need to know its i) electro-negativity and its ii) melting point.

Explanation : i) Electronegativity of any element is a specific value term which helps in identifying the element more precisely as compared to other tests which are given.
ii) Melting point is very specific for every element which will be an essential test to identify the mystery element by the standard melting points of other elements.
