Using the periodic table, elaborate the difference between the number of electrons in an oxygen-16 atom and an oxygen-18 atom.
A) These configurations differ in their number of electrons - so they contain 8 and 9 electrons, respectively.
B) Allotropes vary in their number of electrons - so oxygen-16 and oxygen-18 contain 8 and 10 electrons, respectively.
C) Oxygen atoms fluctuate in their number of electrons - so oxygen-16 and oxygen-18 contain 7 and 9 electrons, respectively.
D) The number of electrons are the same for all isotopes of an element - so both oxygen-16 and oxygen-18 contain 8 electrons.
