10.
a. NH2CH(CH3)COOH
b. The functional group is in bold.
c. carboxylic acid and amine
Explanation:
NH2 is amine (amino acid)
COOH is the carboxylic acid (acetic acid)

Answer:
Where it is on the periodic table
Explanation:
The periodic table is a table that provides a systematic pattern for arranging elements.
The table is based on the periodic law. The modern version of the periodic law states that " the properties of elements are periodic function of their atomic number".
In the modern periodic table, elements having the same number of electrons in their outermost shell are placed over one another in a vertical column.
Elements in the same group exhibits similar chemical properties because of the same number of electrons in their outermost shell. Physical properties also varies progressively down any group.
So, the position of an element on the periodic table determines its properties.
