Alkali metals
The "vertical" column of the periodic table is called the "group" (from group I, with Hydrogen at the top, then Lithium, Sodium, Potasium, Rubidium, Cesium and Francium at the bottom of that group; To group VIII with Helium at the top, working down to ununoctium at the bottom). The horizontal column is called a "period". e.g, period 1, has the element Hydrogen to Helium from left to right of the periodic table, Whereas period 7, has the elements Francium, Radium, Actinium, Rutherfordium, dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Darmstadtium, Roentgenium, Ununbium, Ununtrium, Ununquadium, Ununpentium, Ununhexium, Ununseptium and Ununoctium, from left to right of the periodic table!
The elements listed are Group 1 elements, the Alkali metals. They include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr). Use the link below to check facts and learn more.
To find the period of an element on the periodic table, you look at the end of the row and see what number is there. For example, if your were trying to find the period of Oxygen, you would look all the way to the right or left side of the table and see what number there is, and you would find that oxygen is in period 2.
Hydrogen is the first atom on the periodic table.It has atomic number 1.It is represented by symbol H.
Metallic character increases as one transitions down and right through the periodic table. By definition, francium (Fr) would be the most metallic, but only extremely small amounts of it exist at any given time, thereby rendering caesium (Cs) as the most metallic element.
Hydrogen is found in group 1 row 1 of the periodic table
Sodium can be found in group 1 and it is listed in the periodic table as part of the alkali metal group.
The elements in group one are the alkali metals.
The alkali metals.
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.
The group name of column 1 is alkali metals. They are metallic and basic in nature.
The group no. of Lithium is 1 and its period number is 2.
Sodium is in Group 1 and Period 3 of the periodic table.
Actually group 1 is ALL elements and so is the whole periodic table.
Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
Cesium is found in group 1 of the periodic table.
Helium is in the first period of the periodic table.
