The nucleus of an atom can be asssumed to be spherical. The radius of the nucleus of mass number A is given by 1.25×10−13×A13cm. Radius of atom is one Å. If the mass number is 64, then the fraction of the atomic volume that is occupied by the nucleus is View Solution ...
The nucleus of an atom consists of protons and neutrons (no electrons). A nucleus of a carbon-12 isotope contains six protons and six neutrons, while a nitrogen-14 nucleus comprises seven protons and For the nucleus 79X190, ...
If the radius of a nucleus with mass number 125 is 1.5 fermi then radius of nucleus with mass number 64 is View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class 7, Class 8, Class 9, Class 10, Class 11 and Class 12, IIT JE...
Why is the potassium atom larger than the krypton atom? (a) Krypton has more protons than potassium. (b) There are more positive charges in the krypton nucleus, so the attractive charge of the electron is stronger, and th...
A picometer (pm) is equal to one trillionth of a meter.What is Atomic Radius? To understand the atomic radius definition, one must first consider the subatomic particles: electrons (negatively charged particles) orbit an atom's nucleus (center of the atom), which contains protons (positively ...
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.
The Rutherford formula, as derived, assumes purely elastic scattering from the Coulomb force. No formation of a compound nucleus is considered. Generally, for most of the initial experiments, the ... Jon Custer 8,691 answered Jun 15, 2020 at 14:47 5 votes Distance of subshells from nu...
to be an oversimplification of the atomic structure; the electrons are thought to surround the nucleus inspherical probability zones called shells. However, the Bohr radius is still a useful constant because, in a sense, it represents the smallest mean radius normally attainable by a neutral atom...
