Atomic no. 103. Located in period 7 d-block. Last element of the actinide series.
sodium
The elements located in the first column, group IA on the periodic table, are called alkali metals.
In the old numbering system, "A" simply refered to the the left side of the table. Group IA,IA are alkali metals.
Yes, it is an alkali earth metal in Group 1 (IA) on the periodic table.
Either IA (Hydrogen) or IIIA (Boron)
Alkali Metals, or group IA (One A in roman numerals) and period 3 (3rd level electron shell).
The North America Convention Periodic Table is a variant of the traditional periodic table that places the lanthanides and actinides separately at the bottom of the table, rather than within the main body of the table. This arrangement is done to reduce the width of the table and make it easier to read.
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
Cesium has one valence electrons in its outer ring, as indicated by its placement in column 1 of a wide form periodic table or column IA of a narrow form periodic table.
Group A is an obsolete symbol for groups; the old groups IA and IIA contain alkali metals and alkali earth metals.
Carbon: Carbon is classified in group 14 (IVA) of the periodic table, making it a member of the carbon family. Sodium: Sodium is a member of the alkali metal family and belongs to group 1 (IA) of the periodic table. Oxygen: Oxygen belongs to group 16 (VIA) of the periodic table and is classified in the chalcogen family. Iron: Iron is classified in group 8 (VIII) of the periodic table and is part of the transition metal family.
Metals are generally found on the left side of the periodic table, while nonmetals are typically found on the right side. The dividing line between metals and nonmetals is called the "staircase" or "metalloid line." Elements located along this line, such as boron, silicon, arsenic, and tellurium, exhibit properties of both metals and nonmetals.
