complete the passage to explain what happens to incoming solar radiation when it reaches. Earth solar interacts with the surfaces and objects in the earth system. Energy form radiation may be or taken by a surface or an object in this case the energy goes through the surface and stays in the object. Energy also may be or bounce off a surface or an object in which case the energy does not go through the surface and does not stay in the object.

answer; i believe that the correct answer is (a) potassium(k)

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

po-215 i got it right on the quiz

i believe the answer is true.
