Group number indicates the number of valence electrons or outer electronic configuration. Group 1A elements such as H, Li, K,etc. have 1 valency. Hydrogen also has only one electron. Therfore it is placed in Group 1.
Also, as its atomic number is 1,it is first in the Periodic Table.
Metals have a tendency to donate their valence electrons and form positive ions. Hydrogen also forms a cation generally. Element Sodium (2,8,1) forms a positive ion by donating its 1 electron to Chlorine (2,8,7). Hydrogen also possess the properties of alkali metals as well as halogens, therefore some modern periodic tables have discarded hydrogen or taken as an unimportant element in the table.
Hope this answer would prove useful to you.
What else can I help you with?
What group and row is hydrogen in on the periodic table?
Hydrogen is found in group 1 row 1 of the periodic table
Why is the element hydrogen considered a key part of any covalent bond it is in even though hydrogen is located in Group 1 on the periodic table?
Hydrogen is not considered a key part in any covalent bond. There are many covalent bonds that don't include hydrogen (C-O, N-O, N-C, etc.) Though Hydrogen is in group 1 with metals that do not form covalent bonds, Hydrogen itself does form covalent bonds. Hydrogen is the oddball in the periodic table and appears in group 1 because of the fact that it has only 1 valence electron, like the other elements in that group.
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.
Why hydrogen is located in group 1?
Hydrogen is located in Group 1 of the periodic table based on its electronic configuration and the similarities it shares with the alkali metals in that group. Despite being a nonmetal, hydrogen exhibits properties similar to both alkali metals and nonmetals.
Why is hydrogen in group 1 if it is not a metal?
Hydrogen is in group 1 because it has one electron in its outer shell, similar to other group 1 elements. Additionally, hydrogen can behave like a metal in certain conditions, such as when it loses an electron to form the H+ ion.
In the periodic table although hydrogen is a member of group 1 what is the difference?
Hydrogen is a gas, the other group 1 elements areliquid or solids at Standard Temp & Pressure
Is hydrogen consisdered to be a metal?
No, hydrogen is considered to be strictly a non-metal. Although it can be considered as a group 1 element due to some of its characteristics.
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 group number is hydrogen?
The element Hydrogen is in the group number 1.
Is Hydrogen in group 7?
Hydrogen is not in group 7. It is in group 1 of the periodic table.
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 hydrogens group name and number?
Hydrogen is in Group 1 and is part of the Alkali Metals group.
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 is the hydrogen in group while it is not a metal?
It is in Group 1.
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.
Why give two reason why hydrogen should not be considered as group 1 element?
Hydrogen has properties of both Group 1 and Group 17 elements, making its classification ambiguous. It does not exhibit typical Group 1 characteristics such as similar chemical reactivity to alkali metals or easily losing its electron to form a cation. Additionally, hydrogen forms diatomic molecules in its elemental state, unlike the alkali metals which exist as monatomic species.
