Placing the atoms and determining the number of bond pairs In BaCO3, carbon (C) is the central atom because it is less electronegative than oxygen (O). Electronegativity is a measure of an atom’s ability to attract electrons towards itself in a chemical bond. The central atom in a Lewis structure is typically the least electronegative atom. ![]() Determining the central atom based on electronegativity The total number of valence electrons for BaCO3 can be calculated as follows:Ģ (valence electrons of Ba) + 4 (valence electrons of C) + 3 × 6 (valence electrons of O) = 2 + 4 + 18 = 2 4 valence electrons. Since there are three oxygen atoms in BaCO3, we multiply the number of valence electrons for oxygen by 3. Oxygen (O) is in Group 16 and has 6 valence electrons.Carbon (C) is in Group 14 and has 4 valence electrons.Barium (Ba) is in Group 2 of the periodic table and has 2 valence electrons.To calculate the total number of valence electrons for BaCO3, we need to consider the valence electrons of each atom in the molecule. Valence electrons are the outermost electrons of an atom that participate in chemical bonding.
