Vedclass · Answer

(A) Isotopes are atoms of the same element that have the same atomic number (number of protons and electrons) but different mass numbers due to a different number of neutrons in their nuclei.Since the two oxygen atoms in the sample have the same number of electrons (which defines the element as oxygen) but a different number of neutrons,they are isotopes of oxygen.Therefore,the correct reason is that the two oxygen atoms are isotopes.

In a sample of ethyl ethanoate $(CH_{3}COOC_{2}H_{5})$,the two oxygen atoms have the same number of electrons but different number of neutrons. Which of the following is the correct reason for it?
