Roughly speaking, the radius of an atom is about 10,000 times greater than that of its nucleus. If an atom were magnified so that the radius of its nucleus became 2.0 cm, about the size of a marble, what would be the radius of the atom in miles? (1 mi 5 1609 m.) 如何将EXCEL生...

a very close approximation of the radius of an atom can still be determined by measuring the distance from its nucleus to that of another atom it is bonded with. In a covalent bond — formed by shared electrons
Atomic radius, half the distance between the nuclei of identical neighbouring atoms in the solid form of an element. An atom has no rigid spherical boundary, but it may be thought of as a tiny, dense positive nucleus surrounded by a diffuse negative clou
For a mass as small as a human being, the Schwarzschild radius is of the order of 10-23 cm, much smaller than the nucleus of an atom; for a typical star such as the Sun, it is about 3 km (2 miles). Britannica Quiz All About Astronomy The Schwarzschild radius is named for the ...

Atomic Size & Atomic Radius - Atomic Size is the distance between the center of the nucleus and the outermost shell of electrons is called the atomic radius. Atomic radii can be measured by measuring the distance between the nuclei of atoms in a metal. T
An atom will have different radii depending on the bond it forms, so there is no fixed radius of an atom. Atomic Radii are therefore determined by the bonds they form.
