What is the trend for first ionization energy for the alkali metals?
Within the alkali metals, or group 1, the ionization energy trend is that ionization energy decreases as you move down the group from top to bottom. This is because with each step down, you add an energy level, therefore the one valence electron is farther and farther from the atom's nucleus. So, the attraction between the nucleus and that electron (its electronegativity) decreases. This makes it easier (requires less energy), making the element more reactive. For example, cesium is more reactive than rubidium, which is more reactive than potassium, which is more reactive than sodium...
Is ionization potential and ionization energy same?
Yes. If the units are eV (electron volts) this is called ionization potential, if the units are kJ/mol then this ionization energy. The conversion between the units is:- 96.485 kJ/mol = 1 eV/particle) Historically it was always called ionization potential as that reflected the method of measurement.
Between beryllium and barium which element will have the lower ionization energy?
Barium has more energy levels. So it has lesser ionization energy.
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
Why does rubidium have a smaller ionization energy than iodine?
Strontium(Sr) lies to the right of rubidium(Rb) in the 5th period on the periodic table. Ionization energy (IE) increases as you go from left to right so Sr would have a higher IE than Rb. The actual reason for this is that both of them have their valence electrons in the 5th shell, so they are the same distance from the nucleus, however, Sr has more protons in the nucleus, and thus the attraction of these electrons is greater. Greater attraction means it takes more energy to remove them.

What is the formula for compound rubidium and chlorine?
The compound formed between rubidium and chlorine has the formula RbCl.
Which element between calcium potassium scandium and titanium has the smallest atomic radius?
Atomic radius (in 10^-12 m): K : 231 Ca: 197 Sc: 160 Ti: 146 (smallest)
What is the chemical formula for the compound formed between rubidium and oxygen?
The chemical formula for the compound formed between rubidium and oxygen is rubidium oxide - Rb2O.
What is the difference between rubidium and seslium?
If you mean "What is the difference between rubidium and cesium?" then Rubidium and cesium are two different elements.They have similar properties but cesium is denser and has a higher atomic mass.Cesium also reacts more vigorously with water and air.
Does a reaction occur between rubidium and lithium chloride?
Yes. As long as rubidium is kept away from air it can. But, this is very difficult. Rubidium + Air = Explosion. Formula would be LiCl + Rb --> RbCl + Li.
What is the difference between potassium and potassium glutamate?
The difference between potassium and potassium glutamate is how they are bound as a chemical. Potassium is bonded with chloride while potassium glutamate is bound with gluconate.
Does rubidum carbonate compound have ionic bonds?
Yes, the bonds between rubidium ions and carbonate ions in rubidium carbonate are ionic bonds.
Equation of the reaction of rubidium with water?
Being an alkali metal Rubidium reacts violently with water, the reaction is similar to sodium and water but rubidium like cesium causes violent and explosive reaction with water, besides rubidium is highly reactive it gets rapidly oxidized.
Why cesium has a lower first ionization energy then rubidium?
Caesium has more electron levels than rubidium, because the electrons are further away the attraction between the outer electrons and protons in the nucleus is less. But that's not just the answer. There is also a thing called electron shielding, the negative charges, of the electrons in the energy levels closer to the nucleus, sort of repel the outer electrons so they can't get closer to the nucleus. Since the electrons are further away and have the attraction from the positively charged nucleus reduced, it takes less energy to break the attraction for caesium than rubidium.
Is ionization potential and ionization energy same?
Yes. If the units are eV (electron volts) this is called ionization potential, if the units are kJ/mol then this ionization energy. The conversion between the units is:- 96.485 kJ/mol = 1 eV/particle) Historically it was always called ionization potential as that reflected the method of measurement.
