6 Type the correct answer in each box.
Scientists often have to deal with numbers that are either very large or very small. For example, the radius of the Sun is approximately 696,000
kilometers, while bacterial cells are as small as 1.9 x 10-4 millimeters. Express each number in an alternate form.
In scientific notation, the radius of the Sun is $6,050 x 10
kilometers.
In expanded notation, each bacterial cell is
millimeters wide.

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).
