Kidadl has lots of great name articles to inspire you. These gases have various uses such as lighting, welding, and space exploration, although they are highly unreactive and colorless in nature. They constitute around 0.96% of the atmosphere. Noble Gases are made of Helium, Neon, Argon, Krypton, Xenon, Radon, and the synthetic gas Oganesson. The Halogen group is also the only group where at room temperature all three states of matter can be seen in the elements. These are non-metals which are poor conductors with low melting and boiling points. Halogens consist of Fluorine, Chlorine, Bromine, Iodine, Astatine, and the synthetic element Tennessine. Polonium is only found in trace amounts due to radioactive decay and Livermorium is made only in labs. While Oxygen and Phosphorus are abundant in nature, Selenium and Tellurium are not. Livermorium is a synthetic element that is part of this group. The Chalcogens have the elements Oxygen, Sulfur, Selenium, Tellurium, and the radioactive element Polonium. While Nitrogen and Phosphorus are found naturally, the others are not with Moscovium being a synthetic element only made in labs. The Pnictogens are made of Nitrogen (N), followed by Phosphorus (represented as P), Arsenic (As), Antimony (Sb), Bismuth (Bi), and finally, Moscovium (Mc). Elements in this group and their compounds are usually toxic. Arranged this way, elements in the same group (column. Each next element in a period has one more proton and is less metallic than its predecessor. All elements in a row have the same number of electron shells. Period 1: Shortest period (with 2 elements) Period 2 and 3: Short period (with 8 elements) Period 4 and 5: Long period (with 18 elements) Period 6 and 7: Longest period (with 32 elements) Let me explain each of these Periods in short. A period in the periodic table is a row of chemical elements. Periods in Periodic Table (With Period Names) There are total 7 periods in Periodic Table. All the elements are found in nature quite widely, except Flerovium. In the periodic table of the elements, each numbered row is a period. The Carbon group, consists of Carbon, Silicon, Germanium, Tin, Lead, and Flerovium. Periods in Periodic Table (With Period Names) There are total 7 periods in Periodic Table. Aluminium is an exception in this group as it is found in abundance. They are good conductors but are rarely found in nature. The Boron Group is named after the lead element of Boron. Gold, Iron, and Copper are important such elements. Transition Metals are hard and dense, are good conductors of heat and electricity, and can be bent easily. They include the Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, and Zinc families of elements. The elements from Group 3 to 12 are called Transition Metals. Some elements in this group are Beryllium, Calcium, and Magnesium. They can conduct heat and electricity and can be made into sheets. These elements are found in the crust of the earth and are soft and silvery metals. The second group of elements in the Periodic table is Alkaline Earth metals. Compared to other elements they have a low melting and boiling point.

This group includes the elements Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. Periodic Table GroupsĪlkali metals are soft, ductile, and good conductors of electricity and heat.

alkali, and alkaline-earth metals, tend to be good reducing agents, as their valence electrons, whose radial orbit DEFINES the atomic radius, tend to be readily oxidized.To learn more about different names, take a look at these Royal last names or these Thai last names and meanings. On the other hand, the larger elements, i.e. nitrogen, fluorine, oxygen, TEND to be very powerful oxidants, and this is also manifested by their small atomic size. Excluding the Noble Gases, the smaller atoms from the right hand side, i.e. It follows that the SMALLEST atoms derive the right of the Table as we face it. Of course, the diagram shows NO data (it should do so), but the relative size of the atoms across the Period, and down the Group is clear. And the best metric that illustrates this trend is the well-known diminution of atomic radii across the Period from left to right? And of course, we should look at some data. Now it is a fact that the nuclear charge is SHIELDED very poorly by incomplete electronic shells. The chemistry and atomic structure of the elements is a contest between (i) nuclear charge, conveniently represented by #Z_'the atomic number'#, and (ii) shielding by other electrons. #'Increase in atomic radii down a Group, a column of the Periodic'#'Table.'#
