Answer: The main type of elements found in the upper right part of the periodic table are the Nonmetals. The correct option is C.
Explanation:
The Periodic table of elements describes the properties of elements which varies in regular manner. Some of these chemical properties includes:
--> Ionisation energy
--> Atomic radii
--> Ionic radii
--> Electron affinity
--> electronegativity
--> metallic Character
--> Atomic volume
It organizes known elements based on these chemical properties. From the features of a Periodic table of elements, they occur in;
--> GROUPS(when similar elements are the arranged in numbered columns). These groups are the alkali metals, alkaline earth metals, halogens and noble gases.
--> PERIODS( when arranged in numbered rows).
Every element can either be classified as a metal, nonmetal or semi metal. NONMETALS are poor conductors of heat and electricity. They are clustered in the upper right-hand corner of the periodic table.
