Periods on the Periodic Table go across and are based on the number of unexcited electrons increasing as you read across. Groups on the periodic table are read down the table and share the same number of valence electrons.
The horizontal rows in a periodic table are called 'periods' and the vertical columns are called 'periods'.
the difference between groups (also known as families) and periods is: a group is a column and a period goes across the table remember that
Groups are vertical columns on the periodic table consisting of elements with the same number of valence electrons. Periods are horizontal rows with elements sharing a highest unexcited electron energy level.
Lithium is in the second period and the first group in the Periodic Table of Mendeleev.
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
Oxygen is in Period 2 , Group 16 ( VI A) of periodic table
The difference between a period and a group is that:A periodic is a horizontal row of elements in the periodic table, which simply means the column of the periodic table.A group is a vertical row of elements in the periodic table, which simply means the row of the periodic table.
the difference between groups (also known as families) and periods is: a group is a column and a period goes across the table remember that
A period are the rows going across on a periodic table, a group is the rows going up and down. there is no relation in them.

Nickel is a natural element and technetium is an artificial element.For example technetium is placed in the group 7 and period 5 of the periodic table and nickel is placed in the group 10 and period 4 of the table.
Thallium is in the group 5 and lead in the group 6 of the periodic table.
Sodium, Na, is in group 1 period 3 on the periodic table.
It is in group 18 of the periodic table
6th group 3rd period
Groups are vertical columns on the periodic table consisting of elements with the same number of valence electrons. Periods are horizontal rows with elements sharing a highest unexcited electron energy level.
group four in the periodic table is a carbon group
Lead is in the group 14 of the Periodic Table.
