Question

Describing Links between Atomic Structure and the Periodic Table

How did knowing the number of valence electrons in one
of the alien elements help to identify it? Explain how the
table was used to accomplish this task.

Answer 1

Knowing the number of valence electrons in an element helps identify it, and the periodic table provides a systematic way to determine valence electrons.

Step-by-step explanation:

Knowing the number of valence electrons in an element helps to identify it because the number of valence electrons determines an element's chemical properties. The periodic table, which organizes elements based on their atomic number and electron configuration, provides a systematic way to determine the number of valence electrons. For example, if an element has only one valence electron like hydrogen, it belongs to Group 1 (alkali metals), and if it has six valence electrons like oxygen, it belongs to Group 16 (chalcogens). Alien elements can be identified based on their valence electrons using the periodic table's arrangement and organization.
