An element is the simplest form of matter composed of atoms having identical number of protons in each nucleus.
Atoms of different elements differ from one another in the number of protons and neutrons in the nucleus, and the number of electrons surrounding the nucleus.
Elements which are hard, ductile, brittle, and malleable; possess luster and conduct heat and electricity are termed metals.

The periodic table of the chemical elements, also called the Mendeleev periodic table, is a tabular display of the known chemical elements.
However, Mendeleev plotted a few elements out of strict mass sequence in order to make a better match to the properties of their neighbours in the table, corrected mistakes in the values of several atomic masses, and predicted the existence and properties of a few new elements in the empty cells of his table.
Mendeleev was later vindicated by the discovery of the electronic structure of the elements in the late 19th and early 20th century.

In physics, melting is the process of heating a solid substance to a point (called the melting point) where it turns into a liquid.
Not only is heat required to raise the temperature of the solid to the melting point, but the melting itself requires heat; see also latent heat and heat of fusion.
The melting point and freezing point are usually the same temperature.

The periodic table of the chemical elements is a tabular display of the known chemical elements.
The elements are arranged by electron structure so that many chemical properties vary regularly across the table.
Despite their dramatic differences in mass within the group, their allotropes have very similar properties: They are all highly corrosive (meaning they combine readily with metals to form metal halide salts); chlorine and fluorine are gases, while bromine is a very low-boiling liquid; chlorine and bromine at least are highly colored.

 CHAPTER 8
Each element has a negative initial level of the expansion coefficient, the magnitude of which has the same relation to the magnitude at the transition point as in specific heat; that is, 2/9 in most cases, and 1/9 in some of the electronegative elements.
The magnitude of the constant K that determines the slope of the upper segment of the expansion curve is determined primarily by the temperature of the end point of the solid state.
At the solid end point the thermal motion is also in equilibrium with the inward progression of the natural reference system, as this is the point at which the thermal motion is able to cross the time region boundary without assistance from gravitation.

The periodic table of the chemical elements is a tabular method of displaying the chemical elements, first devised in 1869 by the Russian chemist Dmitri Mendeleev.
In printed tables, each element is usually listed with its element symbol and atomic number; many versions of the table also include the element’s atomic mass and other information, such as its abbreviated electron configuration, electronegativity and most common valence numbers.
Modern quantum mechanical theories of atomic structure explain that elements within the same group have the same electron configurations in their valence shell, which is the largest factor in accounting for their similar chemical properties.
