The elements in group 1 are known as the alkali metals, those in group 2. Groups are numbered 118 from left to right. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. You can sort the elements by clicking on the table headers. Elements in the same group of the periodic table have similar chemical properties.

List of chemical elements in periodic table with atomic number, chemical symbol and atomic weight. noble gas - element from Group 8 of the periodic table (e.g., xenon, argon). nobelium - actinide with element symbol No and atomic number 102. Nitrogen is also known as azote and is a member of the nonmetal group. Use this website at any time when you need to get fast and precise information about atomic or proton number of chemical elements. nitrogen - Nitrogen is the name for the element with atomic number 7 and is represented by the symbol N. There is also some extra summary on every each chemical element which can be found at our website, including the atomic weight of each element, as well as physical and chemical properties of every element and its importance. By using our website, you can do it in just one click and receive short and correct information on this matter. This website is created for those who need to know the atomic number of a central chemical element. The atomic number is marked with the symbol Z, taken from a German word zahl (or atomzahl, which is ' atomic number' in German). Atomic number of an element never changes: for example, the atomic number of oxygen is always 8, and the atomic number of Chlorine is always 18. Also, knowing the atomic number of an element can give us an idea about the position of the element in the Periodic Table. Why is this so? Why is the atomic number so important? First of all, it is the number that makes elements different from one another as it shows the number of protons in their nuclei. This number can be really important and something essential to know, in relation to a certain chemical element which is the issue of our interest at the moment. It is always the whole number and it ranges from 1 to 118, according to the number of the element in the Periodic Table. It is the same as the number of protons that the atom of each element has, so sometimes atomic number is called proton number. We remember from our school chemistry course that every element has its own specific atomic number. Atomic Number of Elements in Periodic Table
