Question

if oxygen has 6 valence electrons and is in group 16 while chlorine has 7 valence electrons and is in group 17, what is the rule between group number and valence electrons?
multiply by 2.
take the absolute inverse of the square root.
subtract 10.
e=mc²

Explanation:

Step1: Analyze Oxygen's data

Oxygen is in Group 16 and has 6 valence electrons. Let's check the options:

• Multiply by 2: \(16\times2 = 32

eq6\) (no)

• Absolute inverse of square root: Not relevant (no)
• Subtract 10: \(16 - 10=6\) (matches)
• \(e = mc^2\): Not related (no)

Step2: Analyze Chlorine's data

Chlorine is in Group 17 and has 7 valence electrons.

• Subtract 10: \(17 - 10 = 7\) (matches)

Answer:

C. Subtract 10. (Assuming the third option is labeled C, with text "Subtract 10.")
