Q A Space Between Atoms

Atoms form bonds in several different ways but they all have similar bond lengths Generally speaking the space between the nucleus of two bonded atoms is around 10-10 meters This is also called one ngstrm () It's approximately the size of the electron cloud of a single atom -Mark (mods by mbw) (published on 08/12/2009)Get price


Sizes of Atoms and Ions

Although some people fall into the trap of visualizing atoms and ions as small hard spheres similar to miniature table-tennis balls or marbles the quantum mechanical model tells us that their shapes and boundaries are much less definite than those images suggest As a result atoms and ions cannot be said to have exact sizes Get price

Covalent Bond Distance Radius and van der Waals Radius

Covalent bond distance covalent radius and van der Waals radius are used to describe the size and distance between atoms Covalent bond distance refers to the distance between the nuclei of two bonded atoms Covalent radius is half of the internuclear separation between the nuclei of two single-bonded atoms of the same species (homonuclear) Get price
