There are three:
Sodium
Magnesium
Aluminum
Group 3 on the periodic table is also known as the Scandium family. It contains known elements such as Scandium and Yttrium and the Lanthanides and Actinides are also associated with this group, although not full members!
Yes, certain elements in the periodic table, such as elements in the third row and beyond, can have an expanded octet, meaning they can have more than eight valence electrons in their outer shell.
The third group in the periodic table has the highest number of elements. It includes 32 elements because the f-block is also included in it.
The electron configuration 1s22s22p63s23p3 is in the third period and belongs to the halogen group (Group 17) on the periodic table.
The columns of the periodic table are called groups (or families). All elements in a group have the same number of electrons in their outer orbital. Furthermore, since many chemical properties are determined by the location of the outermost electrons, elements in the same group will share many common properties.
There are 8 elements in the third period of periodic table. The elements belong to group-1,2,13,14,15,16,17 and 18
The elements in the third group of the periodic table are boron, aluminum, gallium, indium, and thallium. These elements have similar chemical properties due to their shared position in the periodic table. They are commonly referred to as Group 13 elements.
Scandium and Yttrium
The elements in column 18 of a wide form periodic table or Column VIII of a narrow form periodic table, commonly called the noble gases. Also, both elements in the first period, the elements in groups 15, 16, and 17 of the second period, and the element in group 17 of the third period.
Argon is in the third period of the modern periodic table.
Europium
Tantalum
There are eight third period transition elements on the periodic table.
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.
Neptunium is element 93.
Argon (Ar, element number 18) is the last element in the third period of the periodic table.
Group 3 on the periodic table is also known as the Scandium family. It contains known elements such as Scandium and Yttrium and the Lanthanides and Actinides are also associated with this group, although not full members!
