During cold winters, ice can form on small lakes and ponds. Many people enjoy skating on
the ice. Occasionally, a person skates on thin ice and breaks through it.
Use what you learned in the lesson to explain why rescue workers lie flat on the ice
instead of walking upright when reaching out to help rescue a skater.

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 positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions
