Use the symbols of the elements described in the following clues to fill in the blanks that spell out the name of a famous American scientist. Although this scientist was better known as a physicist than as a chemist, the Philadelphia institute that bears his name does include a biochemistry research facility. (1) The oxide of this alkaline earth metal is amphoteric. (2) The element that makes up approximately 3.0% by mass of the human body. (3) The element having a 7\(s^{1}\) valence electron configuration. (4) This element is the alkali metal with the least negative standard reduction potential. Write its symbol in reverse order. (5) The alkali metal whose ion is more concentrated in intracellular fluids as compared with blood plasma. (6) This is the only alkali metal that reacts directly with nitrogen to make a binary compound with formula \(\mathrm{M}_{3} \mathrm{N}\). (7) This element is the first in Group 3A for which the 11 oxidation state is exhibited in stable compounds. Use only the second letter of its symbol.

Step by step solution

01

Identify element from clue 1

The oxide of this alkaline earth metal is amphoteric. The amphoteric oxide belongs to the element beryllium (Be).

02

Identify element from clue 2

The element that makes up approximately 3.0% by mass of the human body is carbon (C).

03

Identify element from clue 3

The element having a 7\(s^{1}\) valence electron configuration is the element, francium (Fr).

04

Identify element from clue 4

This element is the alkali metal with the least negative standard reduction potential. This refers to lithium (Li). Since we have to write its symbol in reverse order, it becomes iL.

05

Identify element from clue 5

The alkali metal whose ion is more concentrated in intracellular fluids as compared with blood plasma is potassium (K).

06

Identify element from clue 6

The only alkali metal that reacts directly with nitrogen to make a binary compound with formula \(\mathrm{M}_{3} \mathrm{N}\) is lithium (Li).

07

Identify element from clue 7

The element from Group 3A for which the +1 oxidation state is exhibited in stable compounds, is thallium (Tl). Using only the second letter of its symbol, we get l. Combining the symbols and letters obtained from each clue: Be - C - Fr - iL - K - Li - l We can spell the name of the famous American scientist: "Benjamin Franklin" (Note: Well-known for his work in physics and electricity, the scientist's name is indeed associated with a biochemistry research facility at the University of Pennsylvania.)
