Electrons are important because they bond atoms together into molecules and are required for electricity. Electrons are subatomic particles that orbit the nucleus of an atom. The electrons are much smaller than the nucle... More »

The valence electrons, the outermost shell of electrons, are the largest determinant of how an atom reacts chemically to other substances in its environment. The number and arrangement of the outermost electron shell are... More »

The electron configuration for sulfur is 1s2 2s2 2p6 3s2 3p4. Sulfur's atomic number is 16; therefore, it has 16 electrons in its outermost energy level. Sulfur needs another two electrons to have a stable arrangement. More »

In chemistry, ionic bonds and covalent bonds are both methods atoms use to combine into larger molecules by swapping or sharing outer electrons. An atom's energy level is determined by the number and configuration of ele... More »

Heat conduction is the transfer of internal energy (microscopic kinetic and potential energy) from a region of higher temperature to one of lower temperature by the interaction of particles like atoms, molecules, ions or... More »

Metals conduct electricity well due to the fact that the outermost electrons in their atoms are held by weak atomic forces, allowing these electrons to flow easily from one atom to another. This flow of electrons is what... More »

Glass is a good electrical insulator because the electrons in the glass are tightly bound to the atoms and do not transfer easily, thus keeping electricity from moving through the glass. Conversely, good electrical condu... More »
