Where is the s block located in the periodic table?
On a periodic table, the "s-block" is the first columns. The elements in the first column have 1 s-electron, and those in the second have 2.
What are the elements in the last column of the periodic table?
There are 114 elements in the periodic table, not just 2.
What is the difference3 between a family of elements and elements in the same period?
a family is a column of elements a period is a row of elements
How many elements are in the 1st row of the periodic table?
In the Periodic Table of Elements there are: 118 Observed Elements 114 Officially Discovered Elements 112 Officially named Elements 92 Naturally Occuring Elements 83 Non-radioactive elements
Elements on very first Periodic Table?
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
What kind of shell does the first period in the periodic table have?
The first period of the periodic table's elements all have 1 energy level.
Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.

How many elements are listed in period 4?
The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups. It sees the first appearance of d-block (which includes transition metals) in the table. Do You Agree? Sincerely, Jocelyn E.Flowers
