The alkali metals are the metals in Group 1 (the first column of the Periodic Table). Hydrogen is also in Group 1, and so is technically considered to be part of the alkali metal group/family. Hydrogen is in fact a non-metal, however, and does not generally exhibit behavior similar to the other Group 1 elements.
Hydrogen. It doesn't belong to any group, but it has to go somewhere... and since its ion is 1+, it usually is found at the top of the first group, the alkalines, whose ions are also 1+.
Hydrogen is included sometimes in the alkali metals group but hydrogen is not a metal.
Hydrogen (H).

Group 1 or alkali metals
Sodium is a representative element belonging to group 1 (s block element)
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.
an alkali metal
Radium is a member of the group 2 (alkaline earth metals) of the periodic table of Mendeleev; the other members are beryllium, calcium, magnesium, strontium, barium. Radium is also a radioactive element.
Hydrogen is in group 1 but is not an alkali metal.

No. Cesium is an alkali metal or group 1 element. Alkaline earth metals are group 2 elements.

Your question does not make sense. Sodium is an element. It is a member of the "alkali metal" group of elements. (Group 1 in the Periodic Table.)
Sodium is a metal in Group 1 and Period 3 of the Periodic table. It is an alkali-metal.
Radium is a member of the group 2 (alkaline earth metals) of the periodic table of Mendeleev; the other members are beryllium, calcium, magnesium, strontium, barium. Radium is also a radioactive element.
Lithium is the smallest(first) member of Group 1 , the Alkali metals.
Fr or Francium is the most reactive alkali metal (group 1)
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.
