Lisa was wearing her lab coat, closed-toed shoes, and gloves, and she had her hair pulled back. she wore her contacts to class, and some of the chemical she was using splashed into her eye. she told her teacher and quickly went to the eyewash station. she immediately started to rinse her eyes. which best explains her error? she should have removed her lab coat. she should have taken off her shoes. she should have removed her contact lenses. she should have wiped her eyes with her gloves.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

the answers would be

the first one and the second one
