Question: Elements of group 1 are called ___...
Elements of group 1 are called ___
Solution
The periodic table, commonly known as the periodic table of elements, is a tabular representation of chemical elements organised by atomic number, electron configuration, and recurrent chemical characteristics. The table's structure reveals periodic patterns. Metals are on the left and nonmetals are on the right in the table's seven rows, known as eras. The elements in the columns, referred to as groupings, have comparable chemical properties.
Complete answer:
The alkali metals are found in Group 1A (or IA) of the periodic table and include hydrogen (H), lithium, sodium, potassium, rubidium, cesium, and francium. These are soft, glossy, low-melting, extremely reactive metals that tarnish when exposed to air (excluding hydrogen). The term originates from the fact that these metals or their oxides produce a basic (alkaline) solution when dissolved in water. Due to their high reactivity, alkali metals are seldom (if ever) discovered in their elemental state in nature, and are instead found as ionic compounds (except for hydrogen).
At normal temperature and pressure, the alkali metals are all lustrous, soft, and extremely reactive metals that quickly shed their outermost electrons to create cations with charge +1. Because of their suppleness, they can all be sliced easily with a knife, revealing a gleaming surface that tarnishes quickly in the air owing to oxidation by atmospheric moisture and oxygen. They must be kept under oil to avoid interaction with air due to their extreme reactivity, and they are only found in nature as salts, never as free elements. The fifth alkali metal, caesium, is the most reactive of all metals. Water reacts with all alkali metals, although the heavier alkali metals react more violently than the lighter ones.
Elements of group 1 are called alkali metals.
Note:
The majority of alkali metals have a wide range of uses. The use of rubidium and caesium in atomic clocks, of which caesium atomic clocks form the foundation of the second, is one of the most well-known uses of the pure elements. The sodium-vapour lamp, which generates light very effectively, is a typical use of sodium compounds. Since antiquity, table salt, also known as sodium chloride, has been utilised. Lithium is used as a psychiatric medicine and in lithium batteries as an anode. Sodium and potassium are also necessary elements, serving as electrolytes in the body, while the other alkali metals, while not essential, have a variety of positive and detrimental effects on the body.
