How do you determine electron density given atomic density?
The electron density is simply deduced from the atomic density as follows : if ne denotes the electron density and na the atomic density then : ne= z na with z being the number of valence electron per atom.
What is the term that defines the areas of electron density around a nucleus?
The term that defines the areas of electron density around a nucleus is the electron cloud or electron shell. These shells represent different energy levels or orbitals where electrons can be found. Each shell can hold a specific number of electrons.
How does the oxidation number indicate if an electron will be lost or gained?
If an atom loses electron, then it will have a positive oxidation number. If an atom gains electron, then it will have a negative oxidation number.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
What is a quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
What is the information about an element on the periodic table?
Depending on the editor of the periodic table: name, symbol, atomic number, density, electron configuration, group, period, melting point, boiling point etc.
Why the electron affinity of fluorine is less than that of chlorine?
Generally electron affinity goes up as you go from left to right across the Periodic Table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine (note that the most electronegative element is fluorine however).The reason that the electron affinity is not as high as might otherwise be predicted for fluorine is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).Note that there are a number of other exceptions to the general rule of electron affinity increasing towards the upper right corner -- see the Related Questions links to the left for an explanation of some of those other exceptions.See also the Web Links to the left for more information about electron affinities and the fluorine-chlorine exception.
What is the electron configuration of atomic number 26?
The electron configuration of iron, atomic number 26, is [Ar]3d64s2. The expanded electron configuration is 1s22s22p63s23p63d64s2.
