No element has alkali metals. Some elements: lithium, sodium, potassium, rubidium, caesium and francium are akali metals.
Sodium is an Alkali metal. Elements in the center of the periodic table are transition metals.
An element in group 2 of the Periodic Table; the alkali earth metals.
Calcium chloride contains an alkali earth metal (calcium, a group 2 element) and a halogen (chlorine). There is no alkali metal. Alkali metals are group 1 elements.
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
No, the element antimony is a member of group 15 with nitrogen, phosphorus, arsenic and bismuth. It is a semi-metal. You may be thinking of Sr, strontium, which is a highly reactive member of the alkali metals.
Potassium belongs to the alkali metal family on the periodic table. It is in Group 1, which is the first column of the periodic table.
They are in group one called the Alkali Metals.Those are alkali metals. They are the most reactive of all the metals, and they are in group 1 of the periodic table, all the way to the left.
The alkali metal, sodium, is an element.
Hydrogen
Francium has the most larger atomic weight and also the largest atomic radius between the alkali metals.
