Hydrogen is in group 1A because it has one electron in its valence shell. But it's probably best to think of hydrogen as a unique, and ubiquitous, element that really belongs with the nonmetals such as boron, carbon, etc.
If you can look at a Periodic Table with the elements grouped in colored categories you will see that hydrogen belongs with about ten other elements called the nonmetals.
Hydrogen is so unique it doesn't fit with any basic category, just in 1A because of 1 electron in the valence shell.

Where are the alkali metals and the halogens located on the periodic table?
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
Which are the family members of lithium?
The family members of lithium are; hydrogen, sodium, potassium, rubidium, caesium and francium.
Which family only contains one non-metal element?
The first group, group IA, contains the alkali metals, but also involves hydrogen, a non-metal. Though hydrogen is physically in the same group, its properties are not representative of the rest of group IA. On some periodic tables, hydrogen will somehow be "split off" from the other elements in the group, indicating that it really doesn't belong.
Definition of alkali metal?
The term, alkaline metal, means any of the Group I metals:lithium,sodium,potassium,rubidium,cesium,francium.
What is the name of the group IA elements?
Alkali Metals
What group on the periodic table has only one nonmetal?
Either IA (Hydrogen) or IIIA (Boron)
What is the most abundant metal in group IA of periodic table?
sodium
In the periodic table elements in the first columns are called what?
The elements located in the first column, group IA on the periodic table, are called alkali metals.
What group of elements on the periodic table do not have individual names?
In the old numbering system, "A" simply refered to the the left side of the table. Group IA,IA are alkali metals.
Is lithium a solid?
Yes, it is an alkali earth metal in Group 1 (IA) on the periodic table.
What are the elements in Group IIA on the periodic table?
Group 2 (IIA) - Alkaline earth metals: Be, Mg, Ca, Sr, Ba, Ra ns2
Where are the alkali metals and the halogens located on the periodic table?
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
What is so special about the members of the lithium row in the periodic table?
It consists of Hydrogen and Alkali metals like lithium (Li), Sodium (Na). The elements in group IA have one electron in their outer shell.
Which are the family members of lithium?
The family members of lithium are; hydrogen, sodium, potassium, rubidium, caesium and francium.
What names are giving in group IA?
Group 1A of the periodic table is called Alkali metals. Hydrogen isn't included in this group often, though sometimes it behaves like the group 1 elements. The Alali metals are lithium, sodium, potassium, rubidium, cesium and francium.
What is the North America Convention Periodic Table?
Periodic table that is represented as group IA - VIIIA for s and p block elements and group IIIB - IIB, including three groups in VIIIB is the Nort America Convention of PT
What has a regular repeating pattern in the periodic table?
Group IA: +1 charge Group II2: +2 charge Group IIIB: +3 charge Group IVB: +4 charge Group VB: -3 charge Group VIB: -2 charge Group VIIB: -1 charge
