¿Qué elemento tiene el mismo número de órbitas que el Hidrógeno? ¿Por qué? ¿Tienen propiedades similares, por qué?

What element has the same number of orbits as Hydrogen? Why? Do they have similar properties, why?

Helium

Explanation:

Helium has the same number of orbitals as hydrogen because they belong to the same period on the periodic table.

Periods are the horizontal arrangement of elements. Elements in the same period are known to have the same number of electronic shell or orbitals.

In period 1 where we have just Hydrogen and Helium, the number of orbitals is 1.

For properties of a specie, elements in the same group which are the vertical arrangement of elements have the same properties. Since both Hydrogen and helium are in different groups, their properties differ.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
