The basic rule is that the tools you use have to be smaller than the things you're using them on.Photo: Inside an atom: electrons are the particles in shells (orbitals) around the nucleus (center).And the same goes for science. The smallest thing you can see with a microscope is ...
Chemical properties were based on the number of electrons in the outermost shell. Elements with full outer shells do not react. Other elements take or give up electrons to get a full outer shell. As it turns out, Bohr's model is also useful for explaining the behavior oflasers, although t...
An atom of silicon has 14 electrons, arranged in three different shells. The first two shells — which hold two and eight electrons respectively — are completely full. The outer shell, however, is only half full, with just four electrons. A silicon atom will always look for ways to fill...

Electrons have very little mass compared to protons and neutrons, and they move very fast in their orbits. The orbits are not circular paths, but rather regions of space where the electrons are most likely to be found. These regions are called orbitals or subshells, and they have different ...
The energy of an electron in nth energy level of an atom is expressed as: En=−13.6Z2n2 Where, Z is the atomic number of the given atom. En is in eV. The energy required to move an electron in an atom from a lower energy level to a...
will behave. For lead, however, the configuration gets very long, because lead has 82 electrons, and so it would be time-consuming to write out in full. However, the "shorthand" electron configuration offers a shortcut that saves a lot of time and makes the configuration easier to read. ...
core electrons electrons in filled shells. covalent bond a bond created as a result of sharing electrons. degenerate orbitals orbitals that have the same energy. dipole a separation of positive and negative charges. dipole moment [&~bf~(|bfmu|)~norm~&] a measure of the separation of charg...
Even though protons define the identity of an element, the number of electrons determines the reactivity of each element, allowing the periodic table to sort elements by similar properties. Electrons are found in different spaces around an atom, which we call electron shells. Each row of the ...
The first two shells are full, the first with two electrons and the second with eight. All that is left are two electrons in the valence shell. Now, the atoms could gain six electrons to make it to eight for a full shell, or it could lose two to make it to a full shell. The se...
