It is in row 1 (period 1).
Hydrogen is found in group 1 row 1 of the periodic table
Period 1 refers to the top row of the periodic table. These elements are Hydrogen and Helium.
The mass number of the most common hydrogen isotope, Hydrogen-1, is one
The atomic number of hydrogen is 1, which means that a hydrogen atom has one proton in its nucleus.
It is hydrogen. This element is the only one in its group because it is extremely unique and shares none of the properties of other gases.
Hydrogen's atomic number, 1, shows that hydrogen should appear in the highest row of the periodic table in the leftmost box of that row.
The smallest element known to man is Hydrogen (H).
Hydrogen is found in group 1 row 1 of the periodic table
It is often referred to as the row header or row heading or row number.
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.
the first row (or period) contains two element: hydrogen and helium both of which are nonmetals.
Period 1 refers to the top row of the periodic table. These elements are Hydrogen and Helium.
The row number describes the period. It signifies the number of shells.
It is the number to the left of the row. For example, the first row heading is "1."
