Hydrogen is mostly said to belong to Alkali metals group because it has one electron in its outermost shell. and has an oxiation state of +1.
But it also sometimes place on the top of Halogens since it also one less electron than completion of orbital and sometimes an oxidation state of -1.
Hydrogen is a controversial element for Periodic Table.

What is the classification hydrogen?
Classification of hydrogen is: group 1, period 1 in the periodic table of Mendeleev; hydrogen is the first element in this table.
What is the only nonmetal in group 14?
Carbon (C)
Out of periods 1-3 out of group 1 which is the most reactive?
The most reactive element of part of Group 1 is the one with the highest atomic number. If hydrogen is considered to be in period 1, then the answer to the question is sodium. If instead hydrogen is considered to be in a 0th period, then the answer to the question is potassium.
What elements have the smallest atomic radius in group 1?
atomic radius increases as you go down the group and decreases as you go across the period therefore the smallest atomic radius for group 14 is carbon.
Is Butane in group 2 of the Periodic Table?
The periodic table lists the elements and not compounds. Butane, C4H10, is an organic molecule / compound and hence is not present on the periodic table. The elements that make up butane (carbon and hydrogen) are present on the periodic table. Carbon: group 14, period 2 Hydrogen: group 1, period 1 Besides, group 2 elements are alkaline earth metals.
What elements are found in group 1 and period 1?
Hydrogen is placed in group-1 and period-1 in the periodic table as hydrogen has only one electron.
In what period is hydrogen located at the periodic table?
Hydrogen is located in Group 1A of the Periodic Table.
Why hydrogen is removed from periodic table?
Hydrogen is, and always will be, Group 1 Period 1.
What period of the periodic table is hydrogen in?
Hydrogen is technically classed as a group one element, as it only has one electron!
What is the classification hydrogen?
Classification of hydrogen is: group 1, period 1 in the periodic table of Mendeleev; hydrogen is the first element in this table.
What are the elements in the first column or group?
Columns are periods, and is different to group. On the Periodic Table; Column = Group Row = Period Group 1 (Top to bottom) = Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, Francium Period 1 (Left to Right) = Hydrogen, Helium
Where can you find the six elements in an organic compound in the periodic table?
carbon (group 14, period 2) hydrogen (group 1, period 1) nitrogen (group 15, period 2) oxygen (group 16, period 2) sulphur (group 16, period 3) halogens (group 17, period 2-5)
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.
Is hydrogen in the periodic table?
Yes, group 1, period 1 symbol: H
What is the only nonmetal in group 14?
Carbon (C)
What is the element in period 4 and group 6?
Chromium is the element in period 4 and group 6.
How many outer electrons do the metals in the first period have in the periodic table?
There are no metals in the first period. Only hydrogen and helium.
