What is the element in period 4 and group 6?
Chromium is the element in period 4 and group 6.
Is francium related to water or caesium?
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.
Rubidium cesium and francium all have one valence electron Which element has the smallest atomic radius?
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.
Which is faster reaction of sodium with oxygen or francium with oxygen?
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.
What is the formula for radioactive francium oxide?
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.
What is the group and period for francium?
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
What period is francium found in?
we can see in the first group
Is francium in period 7?
Yes, francium is in period 7 of the periodic table. It is the seventh element in that period.
Where does francium come in the periodic table?
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
Why was francium not in Mendeleev's periodic table?
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.
What is the class of francium on the periodic table?
Position of francium in the Periodic Table of Mendeleev: group 1 (alkali metals), period 7, atomic number 87.
What is the group number for francium?
Francium is in the group 1 (alkali metals) of the periodic table.
What is the period block and group of the element rn 7s1?
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.
What is the metal in period 6 group 1?
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.
What is francium and the alkali metals?
Francium is a member of the alkali metals group (group 1 of the periodic table).
What block is francium in?
Francium is in the group 1 of the periodic table (alkali metals).
What are the elements in the first column or group?
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
