Answer 2

• Boron
• Silicon
• Tellurium

Step-by-step explanation:

• Elements in the periodic table are either metals, non-metals or metalloids.
• Metals are elements that react by losing electron(s) to attain an octet configuration. They occupy groups I, II and III of the periodic table and the transition metals.
• Non-metals, on the other hand, are elements that react by gaining electron(s) to attain a stable configuration. Examples include halogens and noble gases among others.
• Metalloids are elements in the periodic table that have the properties of both metals and non-metals.
• Other examples of metalloids are arsenic, tellurium, germanium and polonium.
