Question 565: Atoms & Nuclei

Question

If M(A; Z), M
p
and M
n
denote the masses of the nucleus $${}_Z^AX,$$ proton and neutron respectively in units of u (1 u = 931.5 MeV/c
2
) and BE represents its bonding energy in MeV, then

Accepted Answer

Mass defect = ZM
p
+ (A Ã¢ÂÂZ)M
n
Ã¢ÂÂ M(A, Z)
$$ \Rightarrow $$ $${{B.E} \over {{c^2}}}$$ = ZM
p
+ (A Ã¢ÂÂZ)M
n
Ã¢ÂÂ M(A, Z)
$$ 	herefore $$ M(A, Z) = ZM
p
+ (A $$-$$ Z)M
n
$$-$$ $${{B.E} \over {{c^2}}}$$

Answer

M(A, Z) = ZM
p
+ (A $$-$$ Z)M
n
$$-$$ BE

Answer

M(A, Z) = ZM
p
+ (A $$-$$ Z)M
n
+ BE/c
2

Answer

M(A, Z) = ZM
p
+ (A $$-$$ Z)M
n
$$-$$ BE/c
2

Answer

M(A, Z) = ZM
p
+ (A $$-$$ Z)M
n
+ BE
