The element Hydrogen is in the group number 1.
Hydrogen is in Group 1 and is part of the Alkali Metals group.
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.
Lithium is the element with the lowest atomic number in Group 1 (alkali metals), while hydrogen is the element with the lowest atomic number in Group 17 (halogens) and Group 18 (noble gases).
Hydrogen is not in group 7. It is in group 1 of the periodic table.
Hydrogen is a non-metal; it's in group VII
Hydrogen is in Group 1 and is part of the Alkali Metals group.
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.
Lithium is the element with the lowest atomic number in Group 1 (alkali metals), while hydrogen is the element with the lowest atomic number in Group 17 (halogens) and Group 18 (noble gases).
NH2 is not an element but a molecular group known as the amine functional group, specifically an amino group. It consists of one nitrogen atom and two hydrogen atoms. The atomic number of nitrogen (N) is 7, while hydrogen (H) has an atomic number of 1. Therefore, NH2 does not have an atomic number as it is not a single element.
The minimum number of hydrogen atoms present in a carboxylic ester is two: one hydrogen atom attached to the oxygen in the ester functional group and one hydrogen atom on the carbon atom adjacent to the ester group.
beacuse it is more eletronegative and contain one electrons
Hydrogen is not in group 7. It is in group 1 of the periodic table.
Carbon (C)
Group number 1 on the periodic table is known as the alkali metals group. These elements include lithium, sodium, potassium, rubidium, cesium, and francium. They are highly reactive and tend to form ionic compounds with nonmetals.
It is in alkaline group.Not in alkaline earth group.It is in alkaline group because, Hydrogen has maximum oxidation number of +1.It react with Halogens.Displaced by other alkaline metals.
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.
Francium has the largest nucleus in the hydrogen group; it's always the atom in the lowest row (highest period number) of any column in a normal periodic table that has the largest nucleus in that column.
