The d level has 5 sub-levels of orbitals and each carries two electrons so 5 x 2 = 10 maximum electrons. The f level has 7 sub-levels of orbitals and can thus hold 14 electrons total. So each electron added would be another element. Hence, the f-block has 14 different elements.

Why is magnesium different from other elements?
All elements are different from each other, that is why they are called elements. They have a different number of subatomic particles making them different.
Who is responsible for discovery of elements?
Different people found different elements.
Is carbon 13 and nitrogen 14 have he same element?
No. Carbon and Nitrogen are different elements themselves. They don't contain any element within them.
Why do different elements have different properties?
Elements have different properties because elements can be further divided than atoms and can be mixed by another element
Do atoms of different elements have a different number of protons?
Yes, atoms of different elements have a different number of protons.
What do different elements have different numbers of?
Different elements have different numbers of protons. The number of protons identifies the element.
Why atomic number of different elements are different?
Because different elements have different numbers of protons, which determines the atomic number.
