Two bar magnets are placed on a table end to end, and they are allowed to swivel freely about their centers. which describes the arrangement they form?   a) they align so that the north pole of one magnet faces the south pole of the other magnet. b) they align so the two south poles face each other. c) they form a t shape, meaning they are oriented perpendicularly to each other. d) they align so the two north poles face each other.

Hi!

Magnets attract with opposite poles. The reason is the North pole of a magnet's magnetic lines (if that makes any sense) generally flow inwards, making it pulling in, and the South pole's magnetic lines flow outwards, pushing out. If you align two magnets with the same poles together, they will always repel, because they will be flowing in different directions.

However, if you align a north and a south pole together, they will work together, and attract.

Therefore, if you place two magnets randomly, and they're close enough, they'll align so that the north pole of one magnet faces the south pole of the other magnet, or choice A.

no but i do not usually comment or use my voice that much when it comes to social media

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.
