Question

electron dot diagrams for four elements are shown. which element would be found in group 14? a. 1 b. 3 c. 4 d. 2

Explanation:

Step1: Recall group - valence electron relationship

Elements in Group 14 have 4 valence electrons. Electron - dot diagrams (Lewis dot structures) show the number of valence electrons of an element. The number of dots around the element symbol in an electron - dot diagram represents the number of valence electrons.

Step2: Count the number of dots for each element

• For element 1: There are 3 dots.
• For element 2: There are 4 dots.
• For element 3: There are 5 dots.
• For element 4: There are 6 dots.

Answer:

D. 2
