They are called f-block elements.
The first row elements are called lanthanides.
The second row elements are called actinides.
The element that comes last alphabetically in the periodic table is Zirconium (Zr).
The last column of the periodic table is called the noble gases or Group 18 elements. These elements are known for their stable and non-reactive properties due to having a full outer shell of electrons.
There are no 'rows' on the Periodic Table of the Elements.I assume you are talking about Group-18 of the table.Group-18 of the Periodic Table of the Elements are the noble gases. These elements have a full valence shell (8 electrons).
Krypton is a noble gas. It has 8 electrons in the outermost shell. So it is in the last column of the periodic table.
A complete periodic table arranged in periods and groups. The symbol of element and atomic number are mentioned.
The last two periods are called lanthanoids and actinoids. They have different properties.So, they are placed separately.
Zirconium or Zr
The very last row on the right
He didn't, his was the first and last
Zirconium - Zr
The last column of the periodic table of elements
The elements on the right side of the periodic table are called nonmetals. They are typically poor conductors of electricity, have low melting and boiling points, and tend to gain electrons in chemical reactions. Common examples include oxygen, nitrogen, fluorine, and helium.
