Sodium (Na)
D
Neon (Ne)
Verified step by step guidance
1
Identify the group number of each element in the periodic table, as the group number corresponds to the number of valence electrons for main-group elements.
Recall that Carbon (C) is in group 14, so it has 4 valence electrons.
Oxygen (O) is in group 16, so it has 6 valence electrons.
Sodium (Na) is in group 1, so it has 1 valence electron.
Neon (Ne) is in group 18, a noble gas with a full valence shell of 8 electrons, but it is generally inert and does not readily form bonds, meaning it effectively has zero valence electrons available for bonding.
