Which of the following elements has maximum density of nucleus:
a) Si ( A = 30, Z = 14)
b) P ( A = 31, Z = 15)
c) O ( A = 16, Z = 8)
d) All have same density.

b phophorous
  • -4
b) Phosphorus  is the answer i think. as it has the highest atomic no. here .but i didn't get what is A here .
 
  • -4
(4) all the above
  • -3
It will be option b) phosphorus[P]

Si have more density
  • -4
As the which has high value of proton and neutron has high density.so P,Si,O
  • -3
Phosphorus
