Each of the specific ecosystems in the world has its own conditions created by nonliving things. These conditions determine what kinds of living things will be able to thrive there Organisms can only thrive where their needs are being met. Everything in an organism's environment has an effect on it. A temperate zone is an area where the conditions never become too hot or too cold, allowing many different kinds of organisms to thrive

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

girl imma just put my comment here because i need a couple point okurrttt
