Respuesta :
Outer electrons because they revolve around the nucleus and can be multiple more than one
The outer electron of an oxygen atom will have a stronger attraction to the nucleus than the outer electrons of a carbon atom.
In the periodic table, atomic sizes decrease across the period. This decrease in atomic size stems from increase in the size of the nuclear charge.
This implies that as we move from left to right in the periodic table, atoms of elements become smaller due to stronger nuclear attraction as the size of the nuclear charge becomes larger.
Oxygen atom has a nuclear charge of +8 while carbon atom has a nuclear charge of +6. Therefore, outer electron of an oxygen atom will have a stronger attraction to the nucleus than the outer electrons of a carbon atom.
