Why hydrogen is placed in group 1 in periodic table although it acts as a halogen also?

It's in Group 1 because of its atomic number--it seemed the right place to put it.

Why is hydrogen (H) placed with elements in Group 1A?
Properties of Hydrogen. Hydrogen is a nonmetal and is placed above group in the Periodic Table because it has ns1 electron configuration like the alkali metals.
What is the correct placement of hydrogen in the periodic table?
It is placed in group 1, period 1 on the modern periodic table
Why hydrogen is placed above alkali metals and not above non-metals in Modern Periodic Table?
It is much more common for hydrogen to lose an electron and become H+ than it is for it to become H- (like a halogen would), as in a hydride. Because it is possible for either behavior, though, some periodic tables DO show hydrogen in group 17. Some show it in group 1. Some show both, and some show hydrogen sitting in the middle by itself. It's a tricky one.
What does stand l for on the periodic table?
I stands for iodine. It is placed in group-17.
Why does helium and hydrogen does not come in agroup of periodic table?
Helium has 2 valence electrons and hydrogen has 1 electron. So, they are placed in different groups.
In which group is hydrogen in periodic table?
it is placed in group 1
Why was the element hydrogen placed in group 1 of the periodic table?
Hydrogen has one valence electron.
What does the letter H stand for in the periodic table?
"H" stands for Hydrogen on the periodic table.
Why is hydrogen (H) placed with elements in Group 1A?
Properties of Hydrogen. Hydrogen is a nonmetal and is placed above group in the Periodic Table because it has ns1 electron configuration like the alkali metals.
What is the correct placement of hydrogen in the periodic table?
It is placed in group 1, period 1 on the modern periodic table
Why hydrogen in placed 1st in periodic table?
Because it got 1 proton.
What element is not properly located on the periodic table based on the three main regions?
Hydrogen is placed separately. It has one valence electron. It is placed at the top in periodic table.
Why is hydrogen placed first in the periodic table?
Because It has 1 proton. The elements on the periodic table are order by the number of protons.
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.
Why hydorgen become first element in periodic table?
Hydrogen has only 1 electron and hence it is placed at the top in the periodic table.
What element is the only Non Metal to the left of the periodic table?
Hydrogen can be considered as a non metal. It is placed to the left of the periodic table.
Is most likely to be a reason why the element hydrogen is placed in group I of the periodic table?
The valence of hydrogen is 1 and form the cation H+.
