Step 1:: Identify the number of atoms in the molecule
The chemical formula for carbon dioxide is CO^2, which consists of one carbon atom (C) and two oxygen atoms (O).
Step 2:: Recall the number of valence electrons for each atom
Carbon is in the 14th group of the periodic table and has 4 valence electrons. Oxygen is in the 16th group and has 6 valence electrons.
Step 3:: Determine the total number of valence electrons in the molecule
To find the total number of valence electrons in CO^2, we simply add up the valence electrons from each atom: Total valence electrons = Valence electrons from C + Valence electrons from O^1 + Valence electrons from O^2 Total valence electrons = 4 + 6 + 6
Step 4:: Calculate the total number of valence electrons
Total valence electrons = 4 + 6 + 6 Total valence electrons = 16
Final Answer
The total number of outer (valence) electrons in carbon dioxide, CO^2, is 16.
