Question

Which of Al, Au, Br, Ca, Cs, F, H, He, Hg, I, K, Mg, Na, O, P, S, and Si is a constituent (part) of table salt?

A) H (Hydrogen)
B) Na (Sodium)
C) F (Fluorine)
D) O (Oxygen)

Answer 1

The constituent of table salt from the given elements is Na (Sodium), which together with chlorine (Cl) forms the compound sodium chloride (NaCl).

Step-by-step explanation:

The subject of the question is related to the composition of table salt, which is a common substance we encounter in everyday life. Table salt is chemically known as sodium chloride and is represented by the formula NaCl. From the elements listed (Al, Au, Br, Ca, Cs, F, H, He, Hg, I, K, Mg, Na, O, P, S, and Si), the one that is a constituent of table salt is Na, which stands for sodium. As seen in the provided reference materials, table salt is comprised of sodium (Na) and chlorine (Cl) ions, with the sodium ions having the elemental symbol 'Na'. This ion contributes to one half of the sodium chloride compound, in a 1:1 ratio with chlorine. Thus, the correct answer to the student's original question is B) Na (Sodium).
