The second period of the Periodic Table contains 6 different elements. The elements are beryllium, agnesium, calcium, strontium, barium, and radium.
The first three periods of the periodic table are called the first period, second period, and third period.
No. Xenon is not the first period of the periodic table. It is placed in the 5th period of periodic table.
It is in group 18 of the periodic table
No , Iodine is placed in period-5 of the periodic table.
There are no specific names for rows in the periodic table because properties of elements in the rows do not match with one other. If we talk about the groups, then there is always some kind of similarity in the groups. For instance, let us take group-I, they are known as the "Alkali metals" because all of them form alkali solutions when their oxides are dissolved in water.
The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.
The allowed orbital types for the second period of the periodic table are 2s and 2p.
Top row, of the bottom two rows on the Periodic Table. (Period 6, starting at group 4)
The second period. (Rows)
The bottom two rows shown on most periodic tables are:Lanthanide series - which belongs to the 6th periodActinide series - which belongs to the 7th period
The first three periods of the periodic table are called the first period, second period, and third period.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
Lithium is in the second period and the first group in the Periodic Table of Mendeleev.
It is present in the Bottom right corner of the table. It is in 7th period, 18th group.
fluorine
No. Xenon is not the first period of the periodic table. It is placed in the 5th period of periodic table.
Copper is in the fourth period of the Periodic Table.
