A mole is a given name of a quantity. It describes a number of particles and a quantity
of mass. The mole is the atomic mass of element, the formula mass of an ionic compound,
the molecular compound of a molecular compound., and the formula units over molecules. A
mole equals 6.02 * 10(23) molecules for all substances. This is Avogadro’s number is
a constant and is the same for all elements. A mole is also equal to the molecular mass in
a molecular compound and the formula mass in a formula compound.
The element I have chosen is sodium. It has a chemical symbol of Na, which is how it
appears on the periodic table of elements. It is classified as an Alaki Metal and resides
in group one, where it will remain since the periodic table is always the same. As an ion,
it exists with a charge of positive one. This means that it loses one electron when
combining to form a compound. Its atomic mass number is eleven and its atomic weight is
22.9898. It has eleven protons and eleven electrons. Most have twelve neutrons with the
exception of sodium’s one isotope.
The element of sodium was discovered by Sir Humphrey Davy. It was discover sometime
during October in 1807. He used electrolysis and discovered not only sodium, but potassium
too. Sodium’s name origin is soda (Na2CO3).
Sodium has a melting point of 98.7*C and a boiling point of 552.9*C. It is a silvery
color. It has a specific heat is 1.23J/gK. It is 0.4 mochs hard. It is soft and its usual
state is solid. It has a structure of bcc, body centered cubic.
Sodium is a very important element as far as survival goes. It is recognized as a
beneficial element, which is any element which promises plant youth in many species, but
are not absolutely necessary for completion of the plant life cycle. There are other uses
for sodium too. The most common compound is table salt or sodium chloride. Salt is very
important to animal nutrition. Other uses of sodium include Soap, which is a sodium salt
of fatty acids, and lamps.
