When a chemical spill has occurred on your clothes you should

Explanation:  When a chemical spill has occurred on your clothes, following measurements must be taken -

1) If there are acids or bases, neutralize as soon as possible.

2) Do not allow the vapors to spread.

3) Avoid the contact with skin.

4) Avoid area getting contaminated as well.

5) Do all the procedures using disposable gloves and Do not forget to put on your lab coat while performing the experiment.

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.
