Ion | Definition, Chemistry, Examples, & Facts
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field
Covalent bond | Definition, Properties, Examples,
Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons. A bond forms
Electronic Configuration | Cambridge (CIE) AS
When there are three electrons in a p sub-shell, one electron will go into each px, py and pz orbital. The fourth electron in a p sub-shell pairs up with one of the electrons in a px, py or pz orbital. The electrons in titanium occupy
Halogen | Elements, Examples, Properties, Uses,
Halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). Learn
Electromagnetism | Definition, Equations,
For example, the absence of only one electron out of every billion molecules in two 70-kilogram (154-pound) persons standing two metres (two yards) apart would repel them with a 30,000-ton force. On a more familiar
Valence Electrons: Definition, Examples, and Importance for
Valence electrons are the electrons present in the outermost shell (energy level) of an atom. They are responsible for chemical bonding and determining an element''s chemical properties. How
CK12-Foundation
Reactivity of Alkaline Earth Metals All alkaline Earth metals have similar properties because they all have two valence electrons. They readily give up their two valence electrons to achieve a full outer energy level, which is the
Electron Affinity
What is Electron Affinity? Electron affinity is the energy change that occurs when an electron is added to a neutral atom to form a negatively charged ion. It measures the attraction between the incoming electron and the nucleus,
7.3: Electric Potential and Potential Difference
The energy of the electron in electron-volts is numerically the same as the voltage between the plates. For example, a 5000-V potential difference produces 5000-eV electrons. The conceptual construct, namely two parallel
Electronic Configuration | Cambridge (CIE) AS
The principal quantum number indicates: The energy level of a particular shell The energy of the electrons in that shell For example: A 2p electron is in the second shell Therefore, it has an energy corresponding to n
