Question

the radius of hydrogen nucleus is 1.4x10^-15 meters. the entire hydrogen atom has radiuse of .53 A. how many times longer is the atom

A. 7.2x10^-16
B 1.93x10^-15
c. 3.8x10^4
D. 7.2x10^4
E. 3.8x10^14

Answer 1

1 Angstrom=10^-10 meters

Answer 2

huh?

Answer 3

how many times longer is atom=radius of atom/radius of nucleus..

Answer 4

is it b

Answer 5

A and B are out of qs cuz there's no way the radius of nuclues would be longer than the radius of atom ==
atom has radius of 5.3exp-11 , nucleus has radius of 1.4exp-15
dun 4get to times 2 cuz it asks how many times longer the atom. (length atm/length nucleus) So I think the ans is :D << if im wrong(no nid times 2, then it shud be C)...
