b. Ca - Metal, Te - Metal, Ne - Nonmetal, Mn - Nonmetal, In - Metal, S - Nonmetal
c. Ca - Metal, Te - Semimetal, Ne - Nonmetal, Mn - Metal, In - Semimetal, S - Nonmetal
d. Ca - Metal, Te - Nonmetal, Ne - Nonmetal, Mn - Metal, In - Metal, S - Nonmetal

Answer 1

Elements like Ca and In are metals, Ne and S are nonmetals, whereas Te is a semimetal, and Mn is classified as a transition metal.

Step-by-step explanation:

To classify elements such as Ca, Te, Ne, Mn, In, and S according to whether they are metals, nonmetals, or semimetals (metalloids), we utilize the periodic table as a reference. The periodic table arranges elements based on similar properties, including their status as metals, nonmetals, or semimetals.

• Ca (Calcium) is a metal. It's an alkaline earth metal found in group 2 of the periodic table.
• Te (Tellurium) is often characterized as a metal, but it is actually a semimetal (metalloid) as it displays properties of both metals and nonmetals.
• Ne (Neon) is a nonmetal. It is a noble gas located in group 18 of the periodic table.
• Mn (Manganese) is a transition metal found in group 7 of the periodic table.
• In (Indium) is a metal. It belongs to the post-transition metals.
• S (Sulfur) is a nonmetal. It's a member of group 16, which contains elements commonly referred to as chalcogens.
