Elements in group 1?
The elements of 1st group are known as Alkalis and They are said to be in Lithium Family. The element are Lithium (Li) , Sodium (Na) , Potassium (K) , Rubedium (Rb) , Cesium (Cs) , Francium (Fr)
Is the lithium atom bigger than the Cesium atom?
Not at all; the cesium atom is far bigger than the lithium atom.
Which atom lithium or cesium needs more energy to become an ion?
Cesium needs more energy to become an ion than lithium because cesium has a higher ionization energy due to its larger atomic size and greater distance of valence electrons from the nucleus. This makes it more difficult to remove electrons from cesium compared to lithium.
Is lithium or cesium more vigorous in water?
Cesium is more reactive. Down the group reactivity increases.
Is an lithium an metal?
Yes, along with Sodium, Potassium, Rubidium, Cesium and Francium, Lithium is an alkali metal.
Which is more soluble in water among lithium and cesium?
Lithium and cesium are both highly reactive metals that will react violently with water (forming a hydroxide compound and giving off hydrogen gas) so the question of relative solubility doesn't really arise.
Why conductivity of lithium is less than cesium?
The conductivity of lithium is less than cesium because lithium has smaller atomic size and higher ionization energy compared to cesium. This results in weaker metallic bonding and less mobile charge carriers in the lattice structure of lithium, leading to lower conductivity. Additionally, lithium also has a higher tendency to form covalent bonds, which further reduces its conductivity.
Elements in group one?
Lithium, Sodium, Potassium, Rubidium, Cesium, & Francium
What are all the alkaline metals?
Lithium, Sodium, Potassium, Rubidium, Cesium, Francium.
Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
Are lithium sodium potassium rubdium and cesium needed by the human body?
Yes, potassium is essential for proper functioning of muscles and nerves in the human body. Sodium is necessary for maintaining fluid balance and nerve function. However, lithium, rubidium, and cesium are not considered essential for human health and can be toxic in high amounts.
Which one of the alkali metals is the most reactive?
cesium and francium ! lithium is the least reactive
