How many electrons does aluminium have? What are the properties of transition metals? What is an element in the third period (row) of the periodic table with four 3p electrons? While balancing a chemical equation, how can one decide which elements to balance...
How many unpaired electrons are in a cu2+ ion? Electron Pairing Atoms and ions consist of electrons that occupy orbitals somewhere around the nucleus of the atom. Orbitals are spaces around the nucleus that an electron has the greatest likelihood of occupying. Different orbitals have different ene...
There can not be two electrons with spin UP in the same sub-orbital. (Pauli exclusion principal.) Also, when you have a pair of electrons in a sub-orbital, their combined magnetic fields will cancel each other out. In order to show how many electrons are in each orbital, the following...
Fluoropolymers are polymers that include the fluorine atom, which is the key to many of the unique characteristics of PTFE. According to William Raiford, technology manager with DuPont Fluoroproducts, fluorine's electron structure is very stable -- it doesn't share its electrons with other atoms...
Moving electrical charges are responsible for the magnetic field in permanent magnets as well. But a magnet's field doesn't come from a large current traveling through a wire — it comes from the movement of electrons. Many people imagine electrons as tiny particles that orbit an atom's ...
A neutral atom is one that has an equal number of protons and electrons. The positive charge of the protons and the negative charge of the electrons will cancel each other out. In the case of argon, it has 18 protons and thus will be neutral if it has 18 electrons in total betwe...
