The nuclear radius of a certain nucleus is `7.2 fm` and it has charge of `1.28xx 10^(-17) (C)`. Find the number of neutrons inside the nucleus.

The distance of closest approach of a certain nucleus is 7.2 fm and it has a charge of 1.28 xx 10^(-17) C. The number of neutrons inside the nucleus of an atom is

The nuclear radius of a nucelus with nucleon number 16 is 3 xx 10^(-15) m . Then, the nuclear radius of a nucleus with nucleon number 128 is .

The radius of a nucleus is given by r_(0) A^(1//3) where r_(0) = 1.3xx 10^(-15) m and A is the mass number of the nucleus, the Lead nucleus has A = 206. the electrostatic force between two protons in this nucleus is approximately

the radius of ""_(29)Cu^(64) nucleus in fermi is (given ,r_(0) 1.2xx10^(-15) M)

The atom has ....... electrons. (d) An atom of an element has 11 protons, 11 electrons and 12 neutrons. The atomic mass of the atom is ........ (e) If the nucleus of an atom has atomic number 17, mass number 37 and there are 17 electrons outside the nucleus, the number of neutrons in it is ........ (f) Almost all the mass of an atom is concentrated in a small region of space called the ........ (g) Cathode rays are a beam of fast moving ........ (h) The anode rays obtained from hydrogen gas consist of particles called ........ (i) The maximum number of electrons that can be accommodated in L shell are ........ (j) The maximum number of electrons that can go into the M shell is ....... (k) The subatomic particle not present in a hydrogen atom is ......... (l) The electron has .......... charge, the proton has ......... charge, and the neutron has .......... charge.

If radius of the nucleus is 3.5 xx 10 ^(-15)m then find the space or volume occupied by the nucleus.
