Question

why is it helpful for engineers to understand the periodic table?
it helps them pick the right materials for specific jobs
it tells them how to make new elements
it shows which elements are the heaviest
it explains how to turn metals into gases
question 7
what do the letters in the center of each square on the periodic table repres
the elements symbol

Explanation:

The periodic table organizes elements based on their properties. Engineers need materials with specific properties (like conductivity, strength) for different tasks. By understanding the periodic table, they can identify elements (and thus materials made from them) that fit job - requirements. For example, a conductor for electrical wiring (copper, Cu from the periodic table) or a strong lightweight material for aerospace (aluminum - alloy, Al is in the periodic table). The other options are incorrect: making new elements is not an engineering task via periodic - table knowledge in general work, showing heaviest elements is a minor aspect not key for job - material selection, and turning metals to gases is not a common engineering use of the periodic table.

Answer:

It helps them pick the right materials for specific jobs.
