In a sample of any metal, spherical atoms pack closelytogether, but the space between them means that the density of thesample is less than that of the atoms themselves. Iridium (Ir) isone of the densest elements: 22.56 g/cm³. The atomic mass of Iris 192.22 amu, and the mass of the nucleus is 192.18 amu.Determine the density (in g/cm³) of (a) an Ir atom and (b) an Irnucleus. (c) How many Ir atoms placed in a row would extend1.00 cm [radius of Ir atom = 1.36 Å; radius of Ir nucleus = 1.5 femtometers (fm); V of a sphere =(4/3)πr³]?
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
