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.
What else can I help you with?
What is lanthanids?
Lanthanoids is a series of 14 elements starting after lenthanum 57 and it belongs to the 6 period and fblock of the periodic table.
Is carbon 13 and nitrogen 14 have he same element?
No, carbon-13 and nitrogen-14 are not the same element. They are different elements with different atomic numbers, which are the number of protons in their nuclei. Carbon-13 has 6 protons, while nitrogen-14 has 7 protons.
The reason there are fourteen different f-block elements in a period can be described by what statements?
The f-block elements have 14 elements in a period because the f orbital in the f-block can hold a maximum of 14 electrons. This results in 14 elements being accommodated in one row or period of the f-block in the periodic table.
Which elements have different isotopes?
Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc
Are all 14 elements all gases?
There are 118 elements, not 14. Most are solid at room temperature. Only 11 elements are gasses.
How can you tell what elements exist on planet?
94 natural elements and 14 artificial elements
Who is responsible for discovery of elements?
Different people found different elements.
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.
Are carbon 12 carbon 13 and carbon 14 different elements?
No, carbon-12, carbon-13, and carbon-14 are not different elements; they are isotopes of the same element, carbon. They all have the same number of protons (6), which defines them as carbon, but they differ in the number of neutrons—carbon-12 has 6 neutrons, carbon-13 has 7, and carbon-14 has 8. This variation in neutron number results in different atomic masses and some differing properties, particularly in terms of stability and radioactivity.
Why atomic number of different elements are different?
Because different elements have different numbers of protons, which determines the atomic number.
How many elements make up group 7 group 14 and group 18?
There is a total of 17 elements in those groups.
