Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
Chromium is the element in period 4 and group 6.
Francium is an alkali metal, similar to caesium. Water (H2O) is a compound,not an element. Francium, although it is believed to have never been tested, is thought to have been the most reactive element with water. It is among the alkali metals in group 1 on the periodic table of elements.
Francium has the smallest atomic radius among rubidium, cesium, and francium because atomic radius increases as you move down a group in the periodic table. Francium is located at the bottom of Group 1, which means it has the largest nuclear charge pulling the valence electron closer to the nucleus, resulting in a smaller atomic radius.
Francium would react faster with oxygen than sodium because francium is more reactive due to its position in the periodic table. Francium is in Group 1, which means it has only one valence electron that it would readily lose to form a compound with oxygen.
Elements of Group I would have a charge of +1 when ionized. Since the OH ion has a charge of -1, the predicted hydroxide of francium would be FrOH.
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
we can see in the first group
Yes, francium is in period 7 of the periodic table. It is the seventh element in that period.
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.
Position of francium in the Periodic Table of Mendeleev: group 1 (alkali metals), period 7, atomic number 87.
Francium is in the group 1 (alkali metals) of the periodic table.
The element with the electron configuration Rn 7s1 is francium (Fr). It is in period 7, group 1 of the periodic table. Francium is a highly radioactive alkali metal with very limited practical applications due to its extreme rarity and radioactivity.
The metal in period 6 group 1 is francium. Francium is a highly radioactive and rare alkali metal with chemical symbol Fr and atomic number 87. Due to its extreme rarity and radioactivity, it is not commonly found in nature.
Francium is a member of the alkali metals group (group 1 of the periodic table).
Francium is in the group 1 of the periodic table (alkali metals).
Columns are periods, and is different to group. On the Periodic Table; Column = Group Row = Period Group 1 (Top to bottom) = Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, Francium Period 1 (Left to Right) = Hydrogen, Helium
