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.

Why is the s-block called s-block?
The elements in the s-block have their last electrons in their electron configuration in the s-orbital.
Which elements have 2 electrons in their s sublevel?
If you're talking about any s sublevel at all, then any element except hydrogen would fit that. If you're talking specifically about elements that have the s orbital as their valence (outermost) orbital, and also have that valence s orbital filled with 2 electrons, then helium and anything in the second column of the periodic table will all fit that description. (He, Be, Mg, Ca, Sr, Ba, Ra)
The first period in the periodic table represents elements that possess only the first energy level s orbital therefore this period contains?
Two elements
The first period in the periodic table represents elements that possess only the first energy level s orbital therefore this period contains elements?
hydrogen and helium
What elements have four electrons in its outer p orbital?
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
S orbital contains how many elements?
S orbital contains only 2 electrons and not elements.
What does the blocks represent?
For the elements in the s-block, the valence electrons are filled in the s orbital.
Why is the s-block called s-block?
The elements in the s-block have their last electrons in their electron configuration in the s-orbital.
How many electrons can be in the S orbital?
The S orbital contains a maximum of two electrons
Why the name s-block element?
S block elements are named so bcozIn this elements last electron enters the outermost s orbital(i.e. ns1 or ns2).
Which elements have 2 electrons in their s sublevel?
If you're talking about any s sublevel at all, then any element except hydrogen would fit that.

The first period in the periodic table represents elements that possess only the first energy level s orbital therefore this period contains?
Two elements
What are elements with 1 or 2 electrons in the outer energy level called?
Group 1: have 1 valence electrons (half filled s orbital) Group 2: have 2 valence electrons (completely filled s orbital)
The first period in the periodic table represents elements that possess only the first energy level s orbital therefore this period contains elements?
hydrogen and helium
What elements have four electrons in its outer p orbital?
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
Why does the octet rule work mainly for elements in period 2?
This is because the elements in the first period only use their s orbitals, youll notice that Hydrogen is 1S and exists as the diatomic H2 and that Helium has the configuration 2S and exists as free Helium. The reason for this is that any S orbital can only hold two electrons, the octet rule applies when there are S and P orbitals present which can hold up to 8 electrons( 2 from the S orbital and 6 from the D orbital).
How many elements make up period 1?
Only two: hydrogen and helium. This corresponds to the fact that there can be only two s orbital electrons in any electron shell, and the first shell has only s orbital electrons.
