That's right, period 7, group 1.
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
francium only has one valence electron (one electron in the outermost shell).
Francium was named after France, the country it was dicovered in.
Atomic radii have not been measured or calculated based on theoretical principles for all of the elements. However, based on the information available in the wikipedia tables of atomic radii it would appear that the largest atom will prove to be that of francium.
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
In 1869 when D. Mendeleev designed his periodic table any element in the period 7 was known. Today francium is in the group 1, period 7, atomic number 87.
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
Position of francium in the Periodic Table of Mendeleev: group 1 (alkali metals), period 7, atomic number 87.
7 is the atomic number of francium.
The period 7 contain: francium, radium, rutherfordium, dubnium, seaborgium, bohrium, meitnerium, darmstadtium, roentgenium, copernicium, ununtrium, flerovium, ununpentium, livermorium, ununseptium, ununoctium.
This location indicate that francium is an alkali metal, very reactive.
we can see in the first group
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
They all react, but Cesium would be the most reactive, since francium is radioactive we don't consider francium the most reactive.
francium only has one valence electron (one electron in the outermost shell).
