Question

an element has the following properties:

• very highly reactive
• shiny
• excellent conductor of electricity and heat
• commonly found in nature mixed with other elements

based on the model, at which letter location could the element be placed on the periodic table?
(periodic table image with locations a, b, c, d shown)

Explanation:

Step1: Analyze element properties

The element is very highly reactive, shiny, excellent conductor of electricity and heat, and commonly found mixed with other elements. These properties match alkali metals (Group 1) or alkaline earth metals (Group 2), which are on the left side of the periodic table.

Step2: Evaluate locations

• Location A: Left - most, likely Group 1 (alkali metals), which are highly reactive, shiny, good conductors, and often found in compounds (mixed with others).
• Location B: Middle (transition metals) – less reactive than Group 1, not "very highly reactive" as a group.
• Location C: Right - side (non - metals/metalloids) – poor conductors (except some metalloids), not highly reactive in the same way as Group 1.
• Location D: Bottom (lanthanides/actinides) – some are reactive, but Group 1 elements are more commonly associated with the given properties and the left - most position.

Answer:

A. Location A
