Question

how many valence electrons are in co₂? fill in blank

Explanation:

Step1: Determine valence electrons of C

Carbon (C) is in group 14 of the periodic table, so it has 4 valence electrons.

Step2: Determine valence electrons of O

Oxygen (O) is in group 16 of the periodic table, so each O atom has 6 valence electrons.

Step3: Calculate total valence electrons in \(CO_2\)

There is 1 C atom and 2 O atoms in \(CO_2\).
The total valence electrons \(=4+(2\times6)\)
\(=4 + 12\)
\(=16\)

Answer:

16
