Hydrogen is placed in group 1 of the Periodic Table due to its one valence electron, which it can lose to form a cation with a +1 charge, similar to the alkali metals in that group. However, hydrogen's properties are different from typical group 1 elements due to its diatomic nature and other unique characteristics.
Because the first energy level has just space for 2 electron, and group 1 all have 1 electron in their outermost shell

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.
What is group 4 on the periodic table of elements?
Hydrogen is period 1 and group1 element. It has only one electron.
What family on the periodic table is hydrogen?
Hydrogen is in the nonmetal family on the periodic table.
Where is the metal on the periodic table?
Yes, the metals are to the left of the staircase except hydrogen is not one- it is a nonmetal.
Why is the position of hydrogen not justified in periodic table?
The position of hydrogen is not well-defined in the periodic table because it exhibits properties of both alkali metals and halogens. This makes it challenging to categorize hydrogen into a specific group based on its properties alone. Additionally, hydrogen's electronic configuration and chemical behavior do not fit neatly into any one group, further complicating its placement in the periodic table.
What is the group is hydrogen in the periodic table?
group one
Why hydrogen and helium are out of periodic table?
Hydrogen and helium aren't 'out' of the periodic table, hydrogen just has characteristics that match up with group one (very reactive) and helium has characteristics that match up with group 8 (non reactive).
What is the group name for the elements in group one?
Group I of the periodic table is called the Alkali Metals group (Hydrogen-Lithium group)
Were are nonmetals located in the periodic table?
the nonmetals are located in the right of the periodic table and only one (hydrogen) is located in group 1, period 1
What is the OH in periodic table?
OH is the chemical formula for the hydroxide ion, which consists of one oxygen atom and one hydrogen atom. In the periodic table, oxygen is in group 16 and hydrogen is in group 1.
What group on the periodic table has only one nonmetal?
Either IA (Hydrogen) or IIIA (Boron)
What period of the periodic table is hydrogen in?
Hydrogen is technically classed as a group one element, as it only has one electron!
Which element has one valence electrons?
Any element in group 1
Why was the element hydrogen placed in group 1 of the periodic table?
Hydrogen was placed in Group 1 of the periodic table due to its ability to lose one electron to form a +1 ion, similar to the alkali metals in that group. However, hydrogen also exhibits unique properties that differ from the alkali metals, leading to debate about its classification.
Why is hydrogen on the top of modern periodic table?
Hydrogen is placed at the top of the modern periodic table because it has unique properties that do not fit neatly into any specific group. It can behave like a metal or a non-metal depending on the conditions, making it difficult to assign it to a specific group in the table. Additionally, hydrogen is the lightest element, consisting of only one proton and one electron.
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.
Why is hydrogen in the perodic table?
Hydrogen is in the periodic table because it is the lightest and simplest element, with one proton and one electron. It lies at the top of the table because it has only one electron shell.
