What Alkali metal has the highest ionization energy?
lithium
Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
What is the group trend for the ionization energy for the alkali metals?
As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals, Lithium > Sodium > Potassium > Rubidium > Caesium > Francium
Which Alkali metals would undergo the least exothermic reaction with chlorine?
Most likely lithium since it has a the highest ionization energy than the others.
Is lithium more reactive than copper?
Yes, potassium is more reactive than lithium, since although they both need to lose one electron to have full outer shells, potassium's outer electron is furthest from the positive attractions of the nucleus. Therefore, it is easier for potassium to lose its outer electron than it is for lithium. hope that helped
Which element in each pair has a greater first ionization energy Lithium Boron?
Lithium
What Alkali metal has the highest ionization energy?
lithium
Which element has a greater ionization out of Li and O?
Oxygen (1313,9 kJ/mol) has a greater ionzation energy than lithium (520,2 kJ/mol).
Which is greater the second ionization energy of potassium or that of calcium?
potassium is greater in the second ionization energy.
Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
What element has the lowest ionization energy out of Lithium Boron Oxygen Fluorine Neon?
lithium
Which atom lithium or cesium needs more energy to become an ion?
Lithium need more ionization energy.
Why is it easier to lose electrons from a cesium atom than from a lithium atom?
It all has to due with ionization energy. Ionization energy is the energy required to remove an electron from an atom to make it an ion. Cesium has a lower ionization energy than Lithium, so it is easier to remove electrons, and thus lose electrons, from a Cesium atom than a Lithium atom.
Which is least reactive sodium or lithium?
Sodium is more reactive then lithium because Na has a lower ionization energy.
What is the group trend for the ionization energy for the alkali metals?
As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals, Lithium > Sodium > Potassium > Rubidium > Caesium > Francium
Which Alkali metals would undergo the least exothermic reaction with chlorine?
Most likely lithium since it has a the highest ionization energy than the others.
Which has a greater ionization energy beryllium or germanium?
Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol. The general trend (most prominently displayed in the representative elements) in the periodic table is increasing ionization energy across a period, and decreasing ionization energy down a group.
