two elements, hydrogen and helium.
S orbital contains only 2 electrons and not elements.
Two elements
two
with an electron configuration that fills up to 2 electrons in their outermost energy level. This includes hydrogen and helium, which have one and two electrons in their outermost s orbital, respectively.
The first period in the periodic table contains two elements: hydrogen and helium. Hydrogen has one electron in its 1s orbital, while helium has two electrons in its 1s orbital.
The first energy level contains one s orbital, which can hold up to two electrons.
The elements in the s-block have their last electrons in their electron configuration in the s-orbital.
Orbitals don't contain elements. The elements each have specific orbitals based on the number of electrons it has. All of the elements have at least one s orbital. Hydrogen being the simplest element has one electron in the 1s orbital. The s orbital can contain a maximum of 2 electrons.

A wave function describes the behavior of an electron in an atom. An orbital represents a region in space where there is a high probability of finding an electron. The wave function is used to calculate the probability density of an electron in an orbital.
The d orbital is the orbital that only applies to the 3rd orbital and up and it contains 10 electrons.
