The group 1 is alled the alkali metals group.
The group 2 is called the alkaline earth metals group.
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.
Hydrogen is located at number 1 on the Periodic Table.
Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
Hydrogen is located on the first period; the first row in the periodic table.
The most active groups in the periodic table are Group 1 (alkali metals) and Group 17 (halogens). Alkali metals are highly reactive due to their tendency to lose an electron, while halogens are highly reactive due to their tendency to gain an electron to achieve a full outer shell.
Group or familyThis is group 1, the alkali metals
rows are called periods columns are known as groups
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 horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
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.
A horizontal row in the periodic table is called a period. There are seven periods in the periodic table, labeled from 1 to 7. Each period represents the energy levels of the elements within that row.
The 3 major groups are: # Metals - Groups 1-15 and the Inner Transitional Elements # Nonmetals - Groups 1 and 14-18 # Metalloids - Groups 13-17 (Diagonal strip of elements separating the metals from the nonmetals)
The groups 1-12 from the periodic table of Mendeleev contain only metals.
The horizontal rows on the Periodic Table are called periods, while the vertical columns are called groups or families. For instance, iodine is in the same group, but different period to fluorine, chlorine and bromine.
"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 group number 1 and 2 contain metals in the periodic table.
