Period 2 Element (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements with similar behaviour fall into the same vertical columns. The second period contains more elements than the previous period, with eight elements: lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. This situation can be explained by modern theories of atomic structure.
