Calculate the number of neutrons of an element X which is represented

1.	Calculate the number of neutrons of an element X which is represented as 31 15X
Answer» MASS number = No. of protons + No. of NEUTRONS = 31 ∴ Number of neutrons = 31– number of protons = 31–15 = 16

Calculate the number of neutrons of an element X which is represented as 31 15X

Answer»

MASS number = No. of protons + No. of NEUTRONS = 31

∴ Number of neutrons = 31– number of protons

= 31–15
