The nucleus of an atom located at the center of the atom contains nearly all of the atoms mass. This has a positive charge because of the protons inside it. There are also neutrons with zero charge. Electrons are orbiting outside the atom. The answer to this problem is d. <span>contains nearly all of the atoms volume.</span>
Electrons in sigma <span>bonds remain localized between two atoms. Sigma </span><span>bond results from the formation of </span><span>a molecular orbital </span><span>by the end to </span><span>end overlap of atomic </span>orbitals. Electrons<span> in pi</span> bonds can become delocalized between more than two atoms. Pi bonds result from the formation of molecular orbital by side to side overlap of atomic orbitals.
