Let’s consider hydrogen fluoride as an example. The electronegativity of fluorine is greater than hydrogen, and as a result, fluorine pulls all the electrons towards itself and becomes the negative pole. Hydrogen, in turn, has an excess of protons and becomes the positive pole. Such molecules ...
This article presents a personal answer to the question “What is chemistry?”, set out in terms of six propositions. These cover “pureR
What is the molar solubility of CdC2O4 in 0.10 M NH3? Which of the following salts, each of which has a solubility product constant (Ksp) equal to 1.0 x 10^-6, has the lowest molar solubility? (A) MX (B) MX2 (C) MX3 (D) M2X (E) M2X3 How do electronegativity and charge ...
Electronegativity of an atom is a measure of the tendency of an atom to attract the shared electron cloud towards itself in a covalent bond. It depends upon the nuclear charge and the atomic size. The higher the electronegativity, the higher is the tendency of an atom to attract electrons. ...
Why do boron, carbon, and silicon not form simple ions? How do they satisf How is the ionization energy of an anion related to the electronegativity of the parent atom? What is the electron affinity of Al^+ ion? What are the re...

Water's large dipole moment makes it a polar solvent. In polar solvents, the bonded atoms have different electronegativity, which is the tendency of atoms to attract electrons. Polarity can be used to describe the on or off states of bits in computing. Quantum bits subvert this paradigm. Lear...
If you do the same thing with any element, you will reach an indivisible part that has the same properties of the element, like the single paper clip. This indivisible part is called anatom. The idea of the atom was first devised byDemocritusin 530 B.C. In 1808, an English school teac...
forces of attraction between the ions are overcome by the heat released. ionic character formula one way of estimating the ionic character of a bond—that is, the magnitude of the charge separation in a polar covalent bond—is to calculate the difference in electronegativity between the two ...
What is the electronegativity of oxygen? What are some examples of oxidation reduction reactions? What are delocalized electrons? What is the oxidation state of nitrogen in the compound NH4Br? What is the oxidation number of chlorine in NaClO4?
