Because Hydrogen behaves unlike most of the other groups, but has characteristics of Groups 1 and 17 . It can form alloys with metals (like group 1)
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.
The element Hydrogen is in the group number 1.
Hydrogen is not in group 7. It is in group 1 of the periodic table.
Hydrogen is in Group 1 and is part of the Alkali Metals group.
Hydrogen is a non-metal; it's in group VII
None. Hydrogen is in its own group.
No, hydrogen is not its own group on the periodic table. It is located in Group 1, but it is not a typical alkali metal like the elements in that group. Hydrogen is unique because it has properties of both metals and nonmetals, and its placement in the periodic table is a subject of debate among chemists.
Yes, it has some unique properties that set it apart from other nonmetals.
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.
The element Hydrogen is in the group number 1.
Hydrogen is not in group 7. It is in group 1 of the periodic table.
Group 2:Alkaline Earth Metals Groups 3-12: Transitional Metals Groups 13&14: Unnamed Group 15:Pnictogens or Pnicogens) Group 16: Chalcogens Group 17: Halogens Group 18: Noble Gases *excluding hydrogen (hydrogen is in its own group) there are about 18
No, hydrogen is not in the nitrogen family. Hydrogen is a nonmetal and sits in a class of its own in the periodic table because it has unique properties that distinguish it from the other elements. The nitrogen family includes elements such as nitrogen, phosphorus, arsenic, antimony, and bismuth.
Hydrogen is in Group 1 and is part of the Alkali Metals group.
Hydrogen is found in group 1 row 1 of the periodic table
Hydrogen is a non-metal; it's in group VII
Hydrogen is unique among the elements, something of an oddball. It does not fit well into the other groups such as the metalloids, halogens, or alkali metals, so it is given its own group.
