Discover who created the periodic table The periodic table of the elements contains all of the Classification of elements into groups The six noble gases—helium, neon, argon, krypton, xenon, and radon—occur at the ends of the six completed periods and The first group, the Although hydrogen is included in Group 1 (Ia), it is not closely similar to either the alkali metals or the halogens in its chemical properties. It is, however, assigned the

There is no one single or best structure for the periodic table but by whatever consensus there is, the form used here is very useful and the most common. The periodic table is a masterpiece of organised chemical information and the evolution of chemistry's periodic table into the current form is an astonishing achievement. On 1 May 2014 a paper published in 48Ca and 249Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. The radioactive decay of evaporation residues and their α-decay products was studied using a detection setup that allows measurement of decays of single atomic nuclei with very short half-lives. Two decay chains comprising seven α-decays and a spontaneous fission each were identified and assigned to the isotope 294Uus (element 117) and its decay products.

So you have seen the above periodic table labeled with group names (from 1-18). Right? Now let’s see 1-18 individual groups of Periodic table along with their group names. Let’s dive straight into it !! Groups in Periodic Table (With Group Names) There are total 18 different groups in Periodic table. • • • • • • Group 15: Nitrogen group • Group 16: Oxygen group • Group 17: Halogen group • Let me explain each of these groups in short. The elements lying from group 3 to 12 on the periodic table are named as Transition metals and Inner transition metals. The They are placed in the two separate rows at the bottom because they show few different properties. Actually, the elements in the bottom rows are the extension of But as these elements have few different properties, they are grouped as separate elements known as inner transition elements. For detailed information on transition and inner transition metals, read the main articles on Group 13: Boron group Final words Groups are the vertical columns on the periodic table. There are total 18 vertical columns on periodic table. Hence there are 18 groups. The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons. For example; Example of group 1 All the elements of group 1 are highly reactive to water. They are soft and can be cut easily with a kitchen knife. Also all the elements of group 1 have one valence electron. Example of group 18 All the elements of group 18 ...

Copper has been used by humans for as much as 7000 years and elements such as gold, silver, tin, lead and mercury have been known for many thousands of years. However, the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous. The discovery of other elements followed regularly and soon it became necessary to arrange them in some sort of order. The earliest attempt to classify the elements was in 1789, when Antoine Lavoisier grouped the elements based on their properties into gases, non-metals, metals and earths. Several other attempts were made to group elements together over the coming decades. Then in 1869, a Russian scientist called Dmitri Mendeleev produced one of the first practical periodic tables. He wrote the properties of the elements on pieces of card and rearranged them until he realised that, by putting them in order of increasing atomic weight, certain properties of elements regularly occurred. At that time, he had only 50 elements to arrange. Not only did Mendeleev arrange the elements in the correct way, but he also had the foresight to leave gaps for undiscovered elements. Over time these gaps have gradually been filled in as scientists unearthed new elements. For instance they discovered phosphorus when they isolated it from urine. Mendeleev never received a Nobel Prize for his work, but element 101 was named Mendelevium, Md, after him. Not to miss out, element 102, Nobelium, No, is named in honor of Alfred Nobe...
