The group 1 is alled the alkali metals group.
The group 2 is called the alkaline earth metals group.
Alkali and alkaline metals, respectively.
Hydrogen is the first element in the periodic table of Mendeleev - atomic number 1. Hydrogen is placed in the group and period 1 of this table.
In the Period Table of the Elements, there are 18 groups, Groups 1-18.Group 0 does not exist.
Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
Francium has the largest atomic radius in Group 1 of the Periodic Table.
it is the number 1
Group or familyThis is group 1, the alkali metals
Groups, 1 through to 8 (or 0) The internet will tell you details about the individual groups. P.S. The rows are called periods
The columns are groups or families. The rows are periods. The groups are numbered 1 to 18, with certain other distinctions. Group 18 is known as the noble gases. There are also larger groupings in to categories such as metals, non-metals, transistion metals, metaloids, etc.
Rows of the periodic table are called periods.
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
The groups 1-12 from the periodic table of Mendeleev contain only metals.
From right to left (1- 18) on the periodic table. Instead of up and down (1-7) periods go vertically. (rows) groups go horizontally. (columns)
"In the periodic table I'm pretty sure the rows are called groups and the columns are called periods" Unfortunately this answer is wrong. The rows are called Periods, and the columns are called groups. If you look at a periodic table, they'll probably have the group numbers at the top, going from 1 above Hydrogen, and the alkali metals, to 8 (or 18) above helium and the noble gases.
The groups of the periodic table are:Group 1: Alkali MetalsGroup 2: Alkali Earth MetalsGroup 3: BoronGroup 4: CarbonGroup 5: NitrogenGroup 6: OxygenGroup 7: HalogensGroup 8: Noble or Inert Gases
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
1) The elements are arranged according to vertical columns.
With a few exceptions metals are placed in groups 1-13 of the Periodic Table of Mendeleev.
