noble gases atomic number 2 chemical symbol He
Helium is located in period 1 on the periodic table.
Helium is in the first period of the periodic table.
Helium is under group 18 and period 1. This makes helium a noble gas with the most electrons it can possibly have under stable conditions.
The element in the same period as helium that has only one valence electron is lithium. Both helium and lithium are located in Period 1 of the periodic table, with helium in Group 18 (noble gases) and lithium in Group 1 (alkali metals). Lithium has the atomic number 3 and has one electron in its outermost shell, making it highly reactive.
Helium is located on the group 18 and period 1 on the modern periodic table.

Helium is under group 18 and period 1. This makes helium a noble gas with the most electrons it can possibly have under stable conditions.
group 18, period 1
In 18th group (zero group), 1st period. It is the first noble gas.
The element in the same period as helium that has only one valence electron is lithium. Both helium and lithium are located in Period 1 of the periodic table, with helium in Group 18 (noble gases) and lithium in Group 1 (alkali metals). Lithium has the atomic number 3 and has one electron in its outermost shell, making it highly reactive.
Helium is located on the group 18 and period 1 on the modern periodic table.
Helium is a semi-metal(metalloid). Helium belongs to group 8(noble gases) and period 1 in the periodic table. It has a relative atomic mass of 4, an atomic number of 2.
Helium is part of a group called the Noble Gases. This group is made up of six different gases, their names are: Helium (H), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
