What makes a heterogeneous mixture different from a homogeneous mixture? the components are mixed unevenly instead of evenly within the heterogenous mixture. insoluble instead of soluble particles are suspended within the heterogenous mixture. two liquids that normally are not mixable are mixed in a heterogeneous mixture. the components within a heterogeneous mixture are elements instead of compounds.

Will give 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).
