Anions are negatively charged ions formed when an atom gains an electron. The energy in this process is called the electron affinity. What Is an Ion? Atoms have three main components: protons, electrons and neutrons. Neutrons are electrically neutral, and although they play an important part in...
Why is water neutral despite the production of hydrogen ions? Why are chemical equations important in chemical changes? Why are the molecules of hydrocarbons nonpolar? Why is water considered a dipolar molecule? How are cohesion and surface tension related to the chemical properties of wate...
In hindsight, the name "atom", referring to something fundamentally un-splittable, is rather inaccurate. Not only are atoms formed from smaller particles (protons and neutrons, which in turn are formed from quarks, and electrons), but they can also very much be split. Indeed, "splitting the...
Ions are formed when an atom either loses or gains electrons. The number in thesuperscriptwill tell you the magnitude of this change. Say you have Cl-. How many electron, protons and neutrons does this ion have? The process for finding these values is very similar to what was done above...
Thermodynamics of the Al matrix, stoichiometric compounds, and aqueous solution are specified by the TCAL5, SSUB5, and TCAQ3 databases in the Thermo-Calc software, respectively. We addressed the oxygen’s role in oxidation and corrosion via O-containing ions, excluding dissolved gases, i.e. O2...
When toner-coated beads are rolled over the drum, the toner particles find the positively charged ions on the unexposed areas on the drum's surface much more attractive than the weakly charged bead. The same particles are subsequently even more drawn to the electrostatically charged paper. The ...
Why are polyatomic ions not neutral? Do all atoms achieve octet when they bond? What is the relationship between atomic structure and the organization of the periodic table? What is the empirical formula for a compound containing 80.68% mercury, 12.87% oxygen and 6.45 % sulfur? If 3.25 mol ...
For atoms that gain an electron, they take on a net negative charge and become anions. These are just names for the positive and negatively charged ions, to help distinguish them from neutral atoms and from each other. The important thing to understand about ions is that they are the only...
Valence electrons are in the outermost shell and affect how an atom bonds with others. Atoms gain or lose electrons to achieve eight valence electrons (or two for hydrogen and helium), following the octet rule. This rule explains why atoms form ions, covalent bonds, or metallic bonds. ...
