In astrophysics and nuclear physics, it usually refers to iron, cobalt, nickel, chromium, and manganese. Ionization energy (IE): The energy required to remove the outermost electron from an atom or a positive ion in its ground level. Elements of the group have one s-electron in the outer electron shell. When the 3 electrons are lost, a full shell of 8 electrons is exposed, creating more stable conditions. Element names ending with -on are noble gases, which are inert or nonreactive gases at room temperature. They have a strong tendency to donate their valence electron in the last shell to form strong ionic bonds. The system of eighteen groups is generally accepted by the chemistry community, but some dissent exists about membership of several elements. Elements that have names ending with -ine belong to a group of elements called halogens. Group 3-12: metals with varying reactivities. Group 1 elements are often referred to as the "alkali metals". Therefore, the nuclear charge decreases. The new IUPAC scheme was developed to replace both systems as they confusingly used the same names to mean different things. The group 1 of the periodic table contain six elements namely Lithium(Li), Sodium(Na),Potassium(K),Rubidium(Rb),Cesium(Cs) and Francium(Fr).These metals are called alkali metals because they form alkalies( i.e. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids). Sodium salts impart a characteristic orange/yellow colour to flames and orange street lighting is orange because of the presence of sodium in the lamp.

PLAY. Lithium is a solid only about half as dense as water and lithium metal is the least dense metal. It replaces two older incompatible naming schemes, used by the Chemical Abstract Service (CAS, more popular in the US), and by IUPAC before 1990 (more popular in Europe). Disagreements mostly involve elements number 1 and 2 (hydrogen and helium), as well as inner transition metals. Electronic Configuration. Use the periodic table chart by element names in alphabetical order for quick research, reference and lab use. See About the Periodic Table for information on how Group can be used to characterize an element.. Group 1: alkali metals, or lithium family; Group 2: alkaline earth metals, or beryllium family; Group 3: the scandium family See About the Periodic Table for information on how Group can be used to characterize an element. As we move down the group, the atomic radius increases. These elements are metals. Group 7 elements require an electron (to fill the outside electron shell). From MilliporeSigma. In the old IUPAC system the letters A and B were designated to the left (A) and right (B) part of the table, while in the CAS system the letters A and B are designated to main group elements (A) and transition elements (B). They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution. The Periodic Table provides the names, atomic numbers, symbols and atomic weights of known elements. The number proceeds in a linearly increasing fashion for the most part, once on the left of the table, and once on the right (see List of oxidation states of the elements), with some irregularities in the transition metals. Amongst this diversity, scientists have found it useful to use names for various sets of elements, that illustrate similar properties, or their trends of properties. The names of some elements indicate their element group. The table lists only the first IE in eV units. Use the periodic table chart by element names in alphabetical order for quick research, reference and lab use. Group 2: next reactive metals, found in earths crust but not in elemental form. They react with water to produce an alkaline metal hydroxide solution and hydrogen. Calcium (Ca) is in group 2, for it contains two valence electrons. There are 7 elements in group 1 in periodic table. The reactions of the various oxides with water and acids. They have the least nuclear charge in their respective periods. These sets usually do not aim to cover the whole periodic table (as for example period does). Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements. Back to Elements List. Groups 1-2 (except hydrogen) and 13-18 are termed main group elements. Caesium is the most metallic element in the group. Flashcards. In this lesson we will learn what types of compounds the group forms, how these compounds are formed, and what these compounds are used for.
