Carlos goes on a field trip to a local aquarium and learns that sea water contains various types of salt compounds. he also learns that most of the salt compounds in sea water are sodium chloride (nacl). carlos then reviews the periodic table, as shown. which elements would bond to form a salt compound most like sodium chloride? a calcium (ca), sulfur (s), oxygen (o), hydrogen (h) b potassium (k), fluorine (f) c magnesium (mg), bromine (br) d calcium (ca), carbon (c), oxygen (o)

your answer would be A calcium sulfur oxygen and hydrogen because those are the components that makes salt

The correct answer is "calcium (Ca), sulfur (S), oxygen (O), hydrogen (H)"

- 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
