प्रश्न
In a sample of ethyl ethanoate (CH3COOC2H5), 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 ?
पर्याय
one of the oxygen atoms has gained electrons
one of the oxygen atoms has gained protons
the two oxygen atoms are isotopes
the two oxygen atoms are isobars
उत्तर
the two oxygen atoms are isobars
As the number of protons is same but the number of neutrons is different, the mass number of the two oxygen atoms is different. So, these two are isotopes of each other.
