See the definition for isobars in Question 15. Consider boron-12, and write the nuclear symbol for
(a) an isobar of boron-12 with atomic number 6.
(b) a nucleus with 4 protons and 8 neutrons. Is this nucleus an isotope or an isobar of boron-12?
(c) a nucleus with 5 protons and 6 neutrons. Is this nucleus an isotope or an isobar of boron-12?
Reference Question 15:
Nuclei with the same mass number but different atomic numbers are called isobars. Consider Ca-40, Ca-41, K-41 and Ar-41.
(a) Which of these are isobars? Which are isotopes?
(b) What do Ca-40 and Ca-41 have in common?
(c) Correct the statement (if it is incorrect): Atoms of Ca-41, K-41, and Ar-41 have the same number of neutrons.
