Elements Of Group 1 Are Called. Soft and can be cut with a knife. For example, the elements of group 1 are known as the alkali metals, group 2 are the alkaline earth metals, group 17 are the halogens, and group 18 are the noble gases.
See answer (1) best answer. All these six elements are called alkali metals. The group 1 elements other than hydrogen are called the alkali metals.the group 1 elements are:
Correct option is c) the elements of group 1 are called alkali metals because their oxides and hydroxides form alkaline solutions on treating with water. Placed in a vertical column on the far left of the periodic table. Lithium (li) sodium (na) potassium (k) rubidium (rb) cesium (cs) francium (fr).
See answer (1) best answer. Hence there are 18 groups. Because sodium reacts quantitatively with water, this metal (and potassium) is commonly used as a drying agent.
The elements in group 18 are lithium (li), sodium (na), potassium (k), rubidium (rb), caesium (cs), and francium (fr). I mean, on the elements of the first columns of groups are columns impurity tables in these guys not to be confused with periods which are rose. Watch video in app continue on whatsapp.
Also known as alkali metals (see why under chemical properties) shiny when cut, but quickly tarnished upon exposure to air. Now in this reaction, the sodium element reacts with water and forms sodium hydroxide (naoh) which is alkaline solution. Noble gases belong to zero group or group 18 of the periodic table.
For example, the elements of group 1 are known as the alkali metals, group 2 are the alkaline earth metals, group 17 are the halogens, and group 18 are the noble gases. The elements in group 1 of the periodic table are called the alkali metals. Metals are very reactive with chemical reactivity increasing down the group.
