Q. 4.13 - An Introduction to General, Organic, and Biological Chemistry

Question

Using Table 4.4, identify the function of each of the following in the body and classify each as an alkali metal, an alkaline earth metal, a transition element, or a halogen:
 a. Ca
 b. Fe
 c. K
 d. Cl

Step-by-Step Solution

Answer

(a)Ca: Alkaline earth metal

(b)Fe: Metal

(c)K: Alkali metal. 

(d)Cl: Halogen

Part(a) Step1 : Given information.

We have been given that,

Calcium(Ca)

We need to identify it's function and classify it as metal, nonmetal or metalloid.

Part(a) Step2 : Simplify.

Calcium: Alkaline earth metal.

• Essential for bones, teeth.

Part(b) Step1 : Given information.

We have been given that,

Iron(Fe)

We need to identify it's function and classify it as metal, nonmetal or metalloid.

Part(b) Step2 : Simplify.

Iron(Fe): metal 

• Essential for RBCs and oxygen carrier component in hemoglobin.

Part(c) Step1 : Given information.

We have been given that,

Potassium(k)

We need to identify it's function and classify it as metal, nonmetal or metalloid.

Part(c) Step2 : Simplify.

Potassium(k): Alkali metal.

• Most abundant electrolyte inside the cells.
• Essential for nerve impulses and muscle contraction.

Part(d) Step1 : Given information.

We have been given that,

Chlorine(Cl)

We need to identify it's function and classify it as metal, nonmetal or metalloid.

Part(d) Step2 : Simplify.

Chlorine(Cl): Halogen;

• Most prevalent negative ion.
• Stomach acid.
