`(""_(32)Ge^(76),""_(34)Se^(76)) and (""_(14)Si^(30),""_(16)S^(32))` are examples of-

A

isotopes and isobars

B

isobars and isotones

C

isotones and isotopes

D

isobars and isotopes

Text Solution

Verified by Experts

The correct Answer is:
B
`""_(32)Ge^(76)`: protons=32, neutrons=76-32=44
`""_(34)Se^(76):`protons=34, neutrons=76-34=42
Atomic number is different but mass number is same. Hence, they are isobars.
`""_(14)Si^(30):`protons=14, neutrons=30-14=16
`""_(16)S^(32)`: protons=16, neutrons=32-16=16
Same number of neutrons. hence, they are isotones.
