For these reasons, the group 1 elements were unknown until the early 19th century, when Sir Humphry Davy first prepared sodium (Na) and potassium (K) by 

Group 1 Elements The elements in Group 18 are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Group 1 elements are: also known as alkali metals (see why under chemical properties) shiny when cut, but quickly tarnished upon exposure to air soft and can be cut with a knife

The elements of group 1 are called alkali metals because their oxides and hydroxides form alkaline solutions on treating with water. Therefore, the solution

Elements of group-1 are called alkali metals and those of group-2 are called alkaline earth metals. Group-1 elements are called alkali metals as these metals form oxides and hydroxides which combine with water to form alkali. Alkali word is derived from the Arabic word ‘alquis’ meaning plant ashes which are rich in the carbonates of sodium

Group 16 elements. Group 16 elements [non-metals] gain 2 electrons and from an ion ²⁻. Group 15 elements. Group 15 elements [non-metals] gain 3 electrons and from an ion N³⁻. Group 14 elements. Group 14 elements would have to either gain or lose 4 electrons. This is not possible so they cannot react by forming ions.

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air. The name comes from the fact that when these metals or their oxides are dissolved in water, a basic (alkaline

10.1 GROUP 1 ELEMENTS: ALKALI. METALS. The alkali metals show regular trends in their physical and chemical properties with the increasing atomic number.

The six elements of Group 1 in the periodic table are: Lithium (Li) Sodium (Na) Potassium (K) Rubidium (Rb) Cesium (Cs) Francium (Fr). All these six elements are called alkali metals. These elements are placed in the vertical column on the left-hand side of the periodic table. Was this answer helpful? 4.5 (1) (6) (0)
