You can discover this by looking at a Periodic Table of the elements.
The rows of the table are called periods; the columns are called groups.
The second period therefore begins with the element Lithium and ends with the element Neon.
Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, and Neon.
The 2nd period of periodic table consists of eight elements which are , Li,Be,B,C,N,O,F and Ne.
There are 8 elements in period 2.
A period is a row of elements on the periodic table.
There are 32 elements in the 6th period of the periodic table.
litium, and elements in the 2nd period (row) are pretty common
a family is a column of elements a period is a row of elements
There are 114 elements in the periodic table, not just 2.
A period is a row of elements on the periodic table.
There are 32 elements in the 6th period of 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.
A period is the horizontal row on the Periodic Table of the Elements.
An elements period is its row in the Periodic Table.
An elements period is its row in the Periodic Table.

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
A period is a row in the periodic table of elements.
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.
