Question
Which of the following statements is true regarding alkali metals?
Francium is the most abundant of all metals and is therefore the least expensive metal per kilogram.
Lithium is the largest atom within the alkali metal group.
The primary reason that alkali metals are submerged in mineral oil for storage is that the mineral oil changes color when these metals undergo radioactive decay, thereby acting as a color indicator for radiation release.
The outer s1 electrons of alkali metals is very tightly bound to their positive nuclei, rendering these metals fairly non-reactive, chemically.
When a lithium atom loses an electron, the resulting ion has an electron configuration comprised of a noble gas core and a filled p shell: [Noble Gas] p6
The chemical reactions associated with Lithium in a reacted state (such as Lithium Peroxide and Lithium Hydroxide) are useful for applications pertaining to modifying atmospheric composition.
