In this article, we'll break down everything you need to know about the periodic table. From its history and layout to its key elements and groups
SCIENTISTS have written what they believe is the world's smallest periodic table - on a strand of human hair. Elementary .. AN ATTEMPT to create what is believed to be the world's largest scientific Periodic Table has been completed by students from Birmingham Metropolitan College as part of ...
If an atom, or atoms, has a balanced number of electrons (negative charge) and protons (positive charge) they are neutral overall. However, if they are not balanced, they will be charged. These charged species are called ions.
may be formally accepted by the end of 2016. the element has the highest atomic mass and highest atomic number of all elements in the periodic table. it has very unstable radioactive atomic nuclei and is predicted to be in a solid state as it has realistic effects. in the periodic table...
A large portion of this project is building the wooden display case itself as, strangely enough, IKEA doesn’t currently stock a shelving unit that’s in the shape of the periodic table. The individual cells and edge molding are made of pine, the back panel is MDF, and the front of the...

In the periodic table of the elements, elements are arranged in a series of rows (or periods) so that those with similar properties appear in vertical columns. Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more ...
The events that led to the atomic theory unfolded as a series of scientific breakthroughs and puzzles. 1913 was a year of highs and lows in physical sciences. Scientists discovered new, heavy elements that would not fit into the Mendeleev table that classified elements on the basis of atomic ...
