Whois & Analysis for ptable.com

The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties.

This ordering shows periodic trends, such as elements with similar behaviour in the same column.

It also shows four rectangular blocks with some approximately similar chemical properties.

In general, within one row (period) the elements are metals on the left, and non-metals on the right.

Redox (short for reduction–oxidation reaction) is a chemical reaction in which the oxidation states of atoms are changed.

Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes.

Redox reactions include all chemical reactions in which atoms have their oxidation state changed; in general, redox reactions involve the transfer of electrons between chemical species.

The chemical species from which the electron is stripped is said to have been oxidized, while the chemical species to which the electron is added is said to have been reduced.

It can be explained in simple terms:

Isotopes are variants of a particular chemical element which differ in neutron number.

All isotopes of a given element have the same number of protons in each atom.

The term isotope is formed from the Greek roots isos ( "equal") and topos ( "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.

The electron is a subatomic particle, symbol or, with a negative elementary electric charge.

Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.

The electron has a mass that is approximately 1/1836 that of the proton.

Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, ħ.

As it is a fermion, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle.

Like all elementary particles, electrons exhibit properties of both particles and waves: they can collide with other particles and can be diffracted like light.

The are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer De Broglie wavelength for a given energy.

In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom.

This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.

The term, atomic orbital, may also refer to the physical region or space where the electron can be calculated to be present, as defined by the particular mathematical form of the orbital.
