Trivial name of Boron is triels, icosagens. Know everything about Boron Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure.


History of Carbon

The element Carbon was discovered by Ancient Egypt in year N/A in unknown place . Carbon derived its name the Latin word carbo, meaning ‘coal’

Carbon (from Latin:carbo “coal”) is a chemical element with symbol C and atomic number 6. On the periodic table, it is the first (row 2) of six elements in column (group) 14, which have in common the composition of their outer electron shell. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds

How to Locate Carbon on Periodic Table

Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The atomic number increases from left to right. Periodic table starts at top left ( Atomic number 1) and ends at bottom right (atomic number 118). Therefore you can directly look for atomic number 6 to find Carbon on periodic table.

Another way to read periodic table and locate an element is by using group number (column) and period number (row). To locate Carbon on periodic table look for cross section of group 14 and period 2 in the modern periodic table.

Ground State Electronic Configuration of Carbon - neutral Carbon atom

The ground state electronic configuration of Neutral Carbon atom is [He] 2s2 2p2. The portion of Carbon configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [He]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.This is important as it is the Valence electrons 2s2 2p2, electrons in the outermost shell that determine the chemical properties of the element.
