Helium is placed at the top of the group-18 in Periodic Table. Its valence shell contains 2 electrons. It is inert in nature like other elements of group-18.
"He" could refer to Dmitri Mendeleev, the creator of the periodic table. The periodic table is a tabular arrangement of the chemical elements, organized by atomic number, electron configuration, and recurring chemical properties. It allows for the prediction of an element's properties based on its position in the table.
Elements in the same group or column on the periodic table have similar chemical properties. Helium is in group 18 or the Nobel gases. Elements with similar chemical properties would be the rest of the elements below Helium Neon, Argon, Krypton, Xenon, and Radon
Helium has 2 valence electrons and it should theoretically be placed along with group 2 elements. But since helium has completely filled orbitals (as do the noble gases), it is placed along with the noble gases.

Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.

helium is chemically inert and has no chemical properties
Helium is inert. There are no known compounds. It has no chemical properties.
Elements in the same group or column on the periodic table have similar chemical properties. Helium is in group 18 or the Nobel gases. Elements with similar chemical properties would be the rest of the elements below Helium Neon, Argon, Krypton, Xenon, and Radon
Helium has 2 valence electrons and it should theoretically be placed along with group 2 elements. But since helium has completely filled orbitals (as do the noble gases), it is placed along with the noble gases.
Helium, carbon, and potassium are all chemical elements found on the periodic table. They each have distinct properties and uses in various applications.
Helium is the second element on the periodic table and its chemical symbol is He.
Neon (Ne) would have properties most like helium (He) because they are both noble gases in the same group of the periodic table, with similar electron configurations and chemical reactivity.
Helium
no
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Helium does not have chemical properties similar to Br (bromine). Helium is a noble gas and is chemically inert, while bromine is a reactive nonmetal.
