This periodic table of elements provides comprehensive data on the chemical elements including scores of properties, element names in many languages and most known nuclides (Isotopes). Below the table there is a "Periodic Table Sorted By" section with links that will sort chemical elements by vario...

Of course all science classes include some experiments and demos but who has time and resources to do a talk on every element in the periodic table? Not many! So this set of videos looks to be a great resource to me. I plan on watching a number more of them over the next few days...
This number became known as an element’s atomic number. 后来,这个数字被称为元素的原子序数。 Today, elements on the periodic table are arranged by atomic number, which gives a more accurate understanding of element properties. 如今,元素周期表上的元素是按原子序数排列的,这使人们对元素的性质有了...
Every chemical element has a specific atomic number, which provides insight into the number of protons present within its nucleus. All isotopes of an element fall under a single cell on the periodic table, since they all share the same atomic number. ...
Explanation of the structure of the periodic table The number of electron shells an atom has determines what period it belongs to. Each shell is divided into different subshells, which as atomic number increases are filled in roughly this order: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f ...
