Vedclass · Answer

(C) The initial composition of $_{8}O^{16}$ is: Protons $(p)$ = $8$,Neutrons $(n)$ = $8$,Electrons $(e^-)$ = $8$. Mass is primarily determined by protons and neutrons. Initial mass number = $8 + 8 = 16$. New number of neutrons = $8 	imes 2 = 16$. New number of protons remains = $8$. New mass number = $16 + 8 = 24$. Change in mass = $24 - 16 = 8$. Percentage change = $(8 / 16) 	imes 100 = 50\, \% 	ext{ increase}$. Note: Electrons have negligible mass compared to protons and neutrons,so changing the number of electrons does not affect the mass calculation.

If the number of neutrons in $_{8}O^{16}$ is doubled and the number of electrons is halved,what is the percentage change in its mass?
