A low estimate is that the periodic table may end soon after the island of stability, which is expected to center on Z = 126, as the extension of the periodic and nuclides tables is restricted by the proton and the neutron drip lines and stability toward alpha decay and spontaneous fission.

Elements, as they appear on the periodic table, have no net charge. They all have equal numbers of protons (+) and electrons (-). HOWEVER, an atom can gain or lose electrons, which will change its Period in periodic table: 4. Block in periodic table: p. Shell structure: 2.8.18.6. CAS Registry: 7782-49-2. Selenium atoms have 34 electrons and the shell structure is 2.8.18.6.

The way the periodic table is organized can be a big help but associating the elements' names with their chemical symbols works too! This quiz game can help you identify all 118 elements based on their symbol. Some symbols offer an alphabetic clue as to the name of the element Periodic table elements in chemistry are organized in order of increasing atomic number or the full number of protons in the atomic nucleus, names as modern law of periodic table. According to the modern law of the periodic table, the chemical elements are arranged on the basis of electronic structure and properties to classify four categories like s, p, d, and f-block element.

Mendeleev published his periodic table in 1869, along with references to groups of families of elements, and rows or periods of his periodic table. At the same time, Hinrichs wrote that simple lines could be drawn on a periodic table in order to delimit properties of interest, such as elements having metallic lustre (in contrast to those not having such lustre). [26] Seeing chemical elements arranged in the modern periodic table is as familiar as seeing a map of the world, but it was not always so obvious. The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
