an alkali metal
Lithium is the first alkali metal.
Sodium is a metal in Group 1 and Period 3 of the Periodic table. It is an alkali-metal.
Sodium is an Alkali metal. Elements in the center of the periodic table are transition metals.
The first element in a period is an alkali metal.
Yes , Fr is an alkali metal. It is placed in group-1
Sodium is an alkali metal, placed in period 3, group 1 of the periodic table of Mendeleev; the atomic number is 11.
Caesium is an alkali metal, placed in period 6, group 1 of the periodic table of Mendeleev; the atomic number is 55.
Metal oxide is the ionic bond combination of any metal element of the periodic table of elements with oxygen. The alkali metals and alkali earth metals are respectively the first and second columns of elements found on the periodic table. Thus, alkali metal oxides and earth metal oxides are types of metal oxides, but metal oxide does not imply alkali.
yes it is.
All periods begin with an alkali metal, excepting the first which begin with hydrogen..
