Question

There are two atomic species X and Y, such that (X: proton-8, neutron-8; Y: proton-8.
neutron-10)
Which of the following statements is true about X and Y?

OPTIONS:-

a) X and Y are isobars
b) Xand Y have different chemical
properties
c) X and Y have different physical properties
d) All of these
​

Answer 1

Answer:

c.X and Y have different physical properties

Answer 2

Two atomic species X and Y, such that (X: proton-8, neutron-8; Y: proton-8, neutron-10):  X and Y have different physical properties. (option c)

• The chemical properties are almost identical because different isotopes show identical chemical behaviors.
• Physical properties like mass, melting or boiling point, and density are different and depend on the mass of each isotope. X and Y have different masses.
