An indication of the size of an atom in a covalent compoundA compound that consists of molecules in which atoms are attached to one another by covalent bonds; a compound where the solid is soft, that has low melting and boiling points, and with low electrical conductivity in solid and liquid states.; often measured as half the internuclear distanceThe distance between the nuclei of nearest-neighbor atoms or ions in an element or compound. Bond distances and ionic radii are calculated from this quantity because atoms have no discrete edges. between like atomsThe smallest particle of an element that can be involved in chemical combination with another element; an atom consists of protons and neutrons in a tiny, very dense nucleus, surrounded by electrons, which occupy most of its volume. bonded to each other.
