Question

The formation of the center of the x, y, and z atomic as follows protons-x3, 6y,z7 neutrons- x4 ,6y, 7z. Calculate

Answer 1

Isotopes have same number of protons but different number of neutrons.

X and Z have 90 protons but 146 and 148 neutrons respectively.

Thus, X and Z are isotopes.

Isobars have same mass number but different atomic number.

Y has 92 Protons and 146 Neutrons . Its mass number is 92+146=238. Its atomic number is 92.

Z has 90 Protons and 148 Neutrons. Its mass number is 90+148=238. Its atomic number is 90.

Thus, Y and Z are isobars.
