From the given information, the mass number of the nucleus is 200 and the proton number of the nucleus is 77.
00:16
Now, following for part a, the net electrical charge of the nucleus is given by the multiple product of the proton number and the fundamental electronic charge.
00:30
It is 77 times the value of fundamental charge.
00:37
Charge is 1 .6 into 10 to the power minus 19 column which comes out to be equals to 1 .23 into 10 to the power minus 17 coulamps moving to part b the number of neutrons the number of neutrons in a nuclear is determined by the difference of the mass number and the proton number the the proton number is 77.
01:09
Therefore, the neutron number is 123.
01:16
Now, part c asks for the number of nucleons.
01:21
So, a is nothing but the number of nucleons.
01:27
The number of nucleons.
01:32
The number of nucleons means number of protons and neutrons, which is denoted by a.
01:37
Now, for part t, the radius of nucleus is determined by this formula r is equal to r0 to the power r0 a to the power 1 by 3 r0 is a standard constant whose value is 1 .2 into 10 to the power minus 15 meters while e is the mass number which was 200 to the power 1 by 3 what we get finally is 7 .02 into 10 to the 10 to the power minus 15 meters.
02:15
This is the radius of the nucleus.
02:18
Now moving toward the nuclear density.
02:21
It will be given by the mass of the nucleus which is nothing but a into mass of one nucleon.
02:31
This is the total mass of nucleus and divided by the total volume of the nucleus which is nothing but 4x3 pi are cube...
