The radius of a hydrogen nucleus is 1.4x10^(-15) meters. The entire hydrogen atom has a radius of .53 A. How many times larger is the atom than its nucleus?


please help any way you can, thanks so much
 
1.4 x 10^9

how?

first i converted .53 A to 5.3 x 10 ^ -11

then i used both radii to find the area of the atom and its nucleus

(pi r^2)

then i took the area of the atom and divided it by the area of the nucleus to attain the above answer

hope this helped
 
How many times larger is the atom than its nucleus. I assume larger is in terms of radius. It could also mean volume or surface area.

A angstrom is 10^-10 m.
The radius of Hydrogen atom is larger than Hydrogen Nucleus by
0.53 * 10^ -10 / 1.4 * 10^ -15 = ( 0.53/1.4) * 10^ 5 = 0.378 * 10^5

The surface area of the Hydrogen atom is larger than the surface area of Hydrogen nucleus is
( Radius Square of Hydrogen Atom ) / ( Radius Square of Hydrogen Nucleus ) Square the above result given for radius

The volume of the hydrogen atom is larger than the volume of hydrogen nucleus is ( Radius Cube of Hydrogen Atom ) / ( Radius Cube of Hydrogen Nucleus ). Cube of the result given for the radius.
