Alkali metals are: lithium, sodium, potassium, rubidium, caesium and francium.
Francium is similar to caesium.
Lithium, Rubidium, Cesium, Francium. Li , Rb , Cs, and Fr
All the elements in the first column of the periodic table have 1 valence electron.They include: lithium (Li), sodium (Na), postassium (K), rubidium (Rb),cesium (Cs), and Francium (Fr).See the Related Questions for more information.
elements are in the same group since they react similarly to other elements in that group.
Elements in the same group as sodium (Group 1) all contain the same number of outer electrons, which is one. Therefore, there are six elements in the same group as sodium: lithium, potassium, rubidium, cesium, francium, and hydrogen.
Assuming that "least nonmetallic" means the same as "most metallic", francium.
There are more then two: potassium and lithium are the nearest, and there are rubidium, cesium, and francium as well in this group.
Francium is mainly used for scientific research due to its highly unstable and radioactive nature. It has no practical applications outside of research and is primarily used to study the behavior of elements in the same group on the periodic table.
If an element with atomic number 119 was discovered, it would likely belong to the same group as other elements in Group 19 of the periodic table. Elements in the same group share similar characteristics due to their similar electron configurations. Additionally, it may have similar properties to other superheavy elements in the same period, due to its high atomic number.
alkaline metal group(or the group 1 elements, except for hydrogen(H), which is a group 1 element but not an alkali metal) - lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
Francium is a metal, specifically an alkali metal. It is in the same group as sodium and potassium on the periodic table.
Elements in the same group as cesium (Group 1, also known as the alkali metals) would have properties most similar to cesium. This group includes elements like rubidium and francium, which share similar chemical behaviors due to their one valence electron and tendency to form +1 cations.
