What is the characteristic of last element in each period of periodic table?
The last element in each period is a noble element. It is non-reactive.
What group does argon belong to on the periodic table?
Argon (Ar, element number 18) is the last element in the third period of the periodic table.
If an element is the last element in its period what does this mean?
On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
Why does each period in the periodic table end with a noble gas?
Each period in the periodic table ends with a noble gas because they have complete outer electron shells, making them stable and unreactive. This pattern reflects the filling of electron shells in atoms as you move across a period.
How many elements make up period 14?
As of now, there are only 7 periods in the periodic table, with period 7 being the last one. Therefore, there is no period 14 in the current structure of the periodic table, and consequently, it contains zero elements. Future discoveries could potentially lead to the addition of more periods, but as of October 2023, period 14 does not exist.
What is the characteristic of last element in each period of periodic table?
The last element in each period is a noble element. It is non-reactive.
What group does argon belong to on the periodic table?

What element in the periodic table comes last alphabetically?
The element that comes last alphabetically in the periodic table is Zirconium (Zr).
Why does each period in the periodic table end with a noble gas?
Each period in the periodic table ends with a noble gas because they have complete outer electron shells, making them stable and unreactive. This pattern reflects the filling of electron shells in atoms as you move across a period.
Where ia Lawrencium located on the periodic table?
Atomic no. 103. Located in period 7 d-block. Last element of the actinide series.
What period group is krypton in?
Period Number: 4 Group Number: 18
What best describes why krypton is located in the last column on the periodic table?
Krypton is a noble gas. It has 8 electrons in the outermost shell. So it is in the last column of the periodic table.
Where is a complete periodic table?
A complete periodic table arranged in periods and groups. The symbol of element and atomic number are mentioned.
What is the last alphabetical symbol in the periodic table?
Zirconium or Zr
Are radioactive substances the last period of elements (at the bottom of the chart)?
Radioactive substances are not exclusive to the last period of elements on the periodic table, but many of the heaviest elements, particularly those in the actinide and transactinide series, are radioactive. These elements, found at the bottom of the periodic table, typically have unstable nuclei that decay over time. However, there are also radioactive isotopes of lighter elements scattered throughout the periodic table. Thus, while many radioactive elements are at the bottom, not all radioactive substances belong to this category.
What are the noble gases on the periodic table?
The very last row on the right
