Question

l
a) A mono canion of unit charge contains 18 neutrons and
the atomic er, mass number of the ion with its identificati​

Answer 1

Answer:

No. of electrons in the monoatomic anion (X

−1

)=36

No. of electrons in the monoatomic atom (X)=35

Atomic No. = No. of protons = No. of electrons in neutral atom =35

Mass No. = No. of protons + No. of neutrons =35+45=80

Hence the ion must be Br −(bromide ion)
