Hydrogen is the most difficult element to classify because its properties indicate it to belong in different groups.
- Hydrogen can lose an electron to become a +1 ion; this is similar to to alkali metals. It can form compounds that are analogs of alkali metals compounds such as HCl and HNO3.
- Under very high pressure, it has the properties of a metal. Hydrogen can react with several metals such as nickel to form materials that behave as alloys of two metals.
- Hydrogen can gain an electron to become a -1 ion; this is similar to the halogens. It can form compounds that are analogs of halogen compounds such as NaH and CaH2.
- It also forms covalent bonds and is a nonmetal and a gas at standard conditions anyway such as O2 and N2.
- Additionally, the electronegativity of hydrogen is almost an average of the lowest and highest electronegativity. The situation is similar with the first ionisation energy. This means that it could be classed as a metalloid.

What group number is hydrogen?
The element Hydrogen is in the group number 1.
What is the group that hydrogen is in?
Hydrogen is a non-metal; it's in group VII
Is Hydrogen in group 7?
no it is in 1
Why does hydrogen show dual nature?
hydrogen shows dual nature as it resembles the alkali metals of group IA and halogens of group VII A (17)
What group is hydrogen in in the periodic table?
Hydrogen is the first element in the periodic table of Mendeleev - atomic number 1. Hydrogen is placed in the group and period 1 of this table.
What group number is hydrogen?
The element Hydrogen is in the group number 1.
Is hydrogen in the nitrogen family?
No. Hydrogen is in group 1 (along with alkali metals) and nitrogen is in group 15.
What element is not grouped with others in a family what is the usual atomic structure?
Hydrogen is not in a group with other families. It actually is in group 1 of the Periodic Table. It is a diatomic atom when it combines with other elements.
In what period is hydrogen located at the periodic table?
Hydrogen is located in Group 1A of the Periodic Table.
What family do you classify hydrogen in?
None. Hydrogen is in its own group.
What is the group is hydrogen in the periodic table?
group one
Why is the hydrogen in group while it is not a metal?
It is in Group 1.
What group and row is hydrogen in on the periodic table?
Hydrogen is found in group 1 row 1 of the periodic table
What is the group that hydrogen is in?
Hydrogen is a non-metal; it's in group VII
What group 1 element is not an alkali metal?
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.
What column are the alkali metals in?
In the first column, under hydrogen. Although hydrogen is in that column, it is not an alkali metal. Hydrogen is in it's own group, popularized as the "group of one"
In which group is hydrogen in periodic table?
it is placed in group 1
