bond: A strong electrostatic interaction between two ions of opposite charge. Ionic bonds are formed between elements with a large difference in electronegativity, so ionic compounds are often composed of a meta
When an element is referred to as an ion and not a cation or anion, is the charge negative or positive by default?Naming an AnionThe ions formed from nonmetallic elements are often named by affixing the suffix "-ide" to the name of the e...
CONSTITUTION: The catalyst system comprises the phenolate/chlorine complex compound of the following formula: Me<+n> [Z<+m> Clm.L]n. In the formula, (n) is an integer of 1 to 3; (m) is an integer of 1 to 6; Cl is chloride anion; Me is H and/or a metallic cation of the ...
The configurational stability of a vinyl anion can be understood from the relativeinstabilityof intermediate (7) in its inversion process, whereas the corresponding intermediate in the inversion of a vinyl radical (10) is relatively more stable leading to a lower energy barrier to inversion. Is vin...
One way to remember the definitions of cations and anions is to think of the letter "t" in the word cation as looking like a plus symbol. The letter "n" in anion is the starting letter in the word "negative" or is a letter in the word "anion." ...
Nota- bly, the shift of the chlorine atom from para- (cyclogua- nil) to meta-position (Q53) was still tolerated, but at the expense of reduced potency, while the ortho-Cl substi- tution prevented Q52 to acquire an appropriate spatial geometry, likely due to steric hindrance. On the ...
of plus three (N+3). All of these are monatomic ions, even though they have a charge that is more than 1, because they are composed of a single atom. An ion with a positive charge, such as Na+, is called a cation, while one with a negative charge, such as Cl-, is an anion...
Because of its high concentration, Cl is the most important anion in balancing extracellular cations. Hyperchloremic acidosis shifts potassium out of cells. Potassium is the most abundant intracellular cation with an intracellular concentration of approximately 140 mmol/L, and only approximately 2% of ...

Why would sodium react more readily with chlorine? Why does sodium chloride normally exist as a crystal rather than as a molecule composed of one cation and one anion? Why does a solution of sodium chloride in water conduct an electric current? Explain why aqueous ...
