3. students in a science class in marfa, texas, made a poster with a diagram to represent a seasonal change in the northern hemisphere. (position 1 is experiencing winter in the northern hemisphere and experiencing summer in the southern hemisphere). * 2 points captionless image a there are an equal number of hours of daylight and nighttime in the northern hemisphere, and the north pole is tilted away from the sun. b the northern hemisphere has the fewest hours of daylight, and earth’s axis does not tilt at this position. c there are an equal number of hours of daylight and nighttime in the northern hemisphere because earth’s axis is not tilted in this position. d the northern hemisphere has the fewest hours of daylight, and the north pole is tilted away from the sun.

the answer depends on the picture or the diagram.

can you send it, please?

D

Explanation:

The earth isn’t tilted

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.
