Carbon is in period 2 on the periodic table of the elements.
Lanthanoids is a series of 14 elements starting after lenthanum 57 and it belongs to the 6 period and fblock of the periodic table.
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.
Magnesium is in Period 3 of the periodic table. The elements in the same period as magnesium (atomic number 12) include sodium (11), aluminum (13), silicon (14), phosphorus (15), sulfur (16), chlorine (17), and argon (18). These elements share the same highest energy level, which is the third shell in this case.
The six elements commonly recognized as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium and are found in group 14-16
There is a total of 17 elements in those groups.
No, the elements sodium (Na) and magnesium (Mg) are in Period 3, while silicon (Si) is in Period 3 in the periodic table of elements. Sodium is in group 1, magnesium is in group 2, and silicon is in group 14.
Carbon is in period 2 on the periodic table of the elements.

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.
There is only 0.5 of a 14-day period in 1 week.
Silicon (Si) is situated between Aluminium (Al) and Phosphorus (P) in the Periodic Table. Its atomic number is 14, and it belongs to the "metalloids" category of the Table. Its period number is 3 and its group number is 14.
The six elements commonly recognized as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium and are found in group 14-16
