Know everything about Beryllium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure
The element Beryllium was discovered by Louis Nicolas Vauquelin in year 1797 in France . Beryllium derived its name from beryl, a mineral
Beryllium is a chemical element with symbol Be and atomic number 4. It is created through stellar nucleosynthesis and is a relatively rare element in the universe. It is a divalent element which occurs naturally only in combination with other elements in minerals.
How to Locate Beryllium 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 4 to find Beryllium 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 Beryllium on periodic table look for cross section of group 2 and period 2 in the modern periodic table.
Beryllium Atomic Structure and Orbital Properties

Ground State Electronic Configuration of Beryllium - neutral Beryllium atom
The ground state electronic configuration of Neutral Beryllium atom is [He] 2s2. The portion of Beryllium 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, electrons in the outermost shell that determine the chemical properties of the element.
