The alkali metals are group 1, also known as group 1A.
Alkali metals are placed on extreme left in the periodic table.These elements are placed in group-1 of the periodic table.
Group 1
1A
The third group in the periodic table has the highest number of elements. It includes 32 elements because the f-block is also included in it.
first group element or group 1 elements are most reactive.beacuse they are alkali metals and contained only 1 electrons in their ns orbital.also their ionisation potential is very low,so they easily lose electron and execute reaction.
Alkali Earth metals have a single valence electron, and are found in the first group.
Group I (alkali metals) and group II (earth-alkali metals)
sodium belongs to IA group element in periodic table.hence valence is one
Alkali earth metals are placed in the second group of the periodic table of Mendeleev.
This is the group 1, the alkali metals.
Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
Francium is in the group 1 (alkali metals) of the periodic table.
Group 1, Alkali Metals
This is the group 1.
Position of francium in the Periodic Table of Mendeleev: group 1 (alkali metals), period 7, atomic number 87.
Sodium is found in Group 1, also known as the Alkali metals or Lithium family, Period 3, with an atomic number of 11 and is represented by the symbol "Na".
The number usually shown on the periodic table is the atomic number of the element, the number of protons, and therefore the number of electrons in the neutral atom.
Crack a book and look at a periodic table. The group is the number at the top of the verticle columns. Alkali metals are group 1A.
The third group in the periodic table has the highest number of elements. It includes 32 elements because the f-block is also included in it.
Apart from Hydrogen, Helium and Beryllium; non metals are located in the p-block. Starting from the third period with addition of Li, all of s-block elements are metals. The d-block elements are a compete set of metals.
