the electron dot diagram shows the arrangement of dots without identifying the element. which elements symbol could replace the question mark in the diagram? o boron (b) o neon (ne) o rubidium (rb) o arsenic (as)

Answer

Answer:

D. arsenic (As)

Explanation:

Step1: Analyze electron - dot diagram

The electron - dot diagram shows 5 dots, representing valence electrons.

Step2: Determine valence electrons of each element

Boron (B) has 3 valence electrons, neon (Ne) has 8 valence electrons, rubidium (Rb) has 1 valence electron, and arsenic (As) has 5 valence electrons. So arsenic (As) is the correct answer.
