What is the electron dot structure for bromine? Boiling point of CH3OH? Explain which of the compounds hexane, 3-hexanon, and 1-hexanol is expected to have the highest boiling point and which one has the lowest boiling point. What is acetone's melting point?
What determines whether or not an atom is reactive? What determines whether or not two atoms will bond to form a molecule? What determines the chemical properties of an atom? How is electron affinity different from electronegativity? How does electronegativity increase?
Boron nitride is a material in which the extra electron of nitrogen (with respect to carbon) enables it to form structures that are isoelectronic with carbon allotropes.Boronnitride is manufactured by heatingboron oxide to 800°C on an acid-solublecarrier, such as calcium phosphate,in the presen...
When it does it becomes an oxide ions which have a charge of -2. Some oxides are highly significant such as Iron II oxide which is commonly called rust. Electron Configuration:Originally the electrons associated with an atom were viewed as being in a cloud around the positive nucleus, ...
screenwriting from the American Film Institute, Jessica Ellis brings a unique perspective to her work as a writer for All The Science. While passionate about drama and film, Jessica enjoys learning and writing about a wide range of topics, creating content that is both informative and engaging ...
The question is, is the electron a mysterious entity which sometimes behaves like a particle and sometimes like a wave, or is it simply a particle which derives its wave-behaviour from a sub-electronic medium, in the same kind of way that a buoy does from the sea, or a pollen grain ...
atomic nucleus in 1911 when he attempted to pass a beam of alpha particles through a thin sheet of gold foil. Rather than passing through the sheet unimpeded, some of the alpha particles bounced back. This showed Rutherford that the previous model for the structure of the atom was not ...
Semiconductors are of 2 Types:An N-type semiconductor is one that carries current in the form of negatively-charged electrons. This is very similar to conduction of current in a wire. A P-type semiconductor is one that carries current predominantly as electron deficiencies called holes. A hole...
It is the energy difference between the top of the valence band and the bottom of the conduction band. It represents the minimum energy required for an electron to transition from the valence band to the conduction band. The size of the band gap is a critical factor in det...
What is the electron configuration for boron? Using the Lewis structure that obeys the octet rule, what is the formal charge of sulfur in the SO4^(2-) ion? What is the electron configuration for the Fe2+ ion? How many electrons are in sulfur?
