What else can I help you with?
Which element would you expect to be the most reactive in group 1 and group 2?
In Group 1, cesium (Cs) is expected to be the most reactive element, as reactivity increases down the group due to the increasing atomic radius and the decreasing ionization energy. In Group 2, barium (Ba) is typically the most reactive, as reactivity also increases down this group for similar reasons—larger atomic size and lower ionization energy. Both cesium and barium readily lose their outermost electrons, making them highly reactive.
Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
What is the parent radioisotope if a beta decay produces barium-137?
Cesium-137
What element has the atomic mass of 56?
The element with an atomic number of 51 is Sb - Antimony; atomic weight = 121.75.
What is ionization energy and which element has the lowest ionization energy?
The energy required for an element to ionize and helium has the lowest.
Does potassium has a higher ionization energy than cesium?
No, cesium has a lower ionization energy than potassium. This is because cesium has a larger atomic size and a weaker attraction between the nucleus and the outermost electron compared to potassium.

The elements cesium Barium and lutetium appear from left to right in Period 6 of the periodic table Among these elements the most reactive is?
Cesium (Cs) is the most reactive among cesium, barium, and lutetium because it is located at the far left of Period 6, making it the largest and having the lowest ionization energy. This means cesium readily loses an electron to form Cs+ ions, exhibiting high reactivity.
Of the following elements which one would have the largest ionization energy Hydrogen (H atomic 1) Cesium (Cs atomic 55) Sodium (Na atomic 11) Potassium (K atomic 19)?
Cesium (Cs) would have the largest ionization energy because it is the element with the highest atomic number in the list. As you move across a period from left to right, the ionization energy generally increases due to increasing effective nuclear charge. Therefore, Cesium would have the highest ionization energy followed by Potassium, Sodium, and then Hydrogen.
What element has the larger first ionization energy cesium or potassium?
Cesium has a larger first ionization energy compared to potassium. This is because cesium is located further down the periodic table in the alkali metal group, meaning it has a larger atomic radius and a lower effective nuclear charge, both of which make it easier to remove an electron from potassium than from cesium.
Which is more reactive barium or cesium?
Cesium is more reactive than barium. Cesium is located lower down in Group 1 of the periodic table, making it more reactive than barium, which is further up the group. Cesium readily reacts with air and water, while barium is less reactive in comparison.
The elements cesium Cs Barium Ba and lutetium Lu appear from left to right in Period 6 of the periodic table Among these elements the most reactive is?
The most reactive element among cesium (Cs), barium (Ba), and lutetium (Lu) is cesium (Cs). Cesium is located at the far left of Period 6 in the periodic table and has a single valence electron, which makes it highly reactive.
Why are Ionization potential decreases Lithium to Cesium?
The ionization potential decreases from lithium to cesium because the atomic size increases, leading to a greater distance between the outermost electron and the nucleus. This increased distance results in weaker attraction between the electron and the nucleus, making it easier to remove the outermost electron and therefore requiring less energy.
What is the parent radioisotope if a beta decay produces barium-137?
Cesium-137
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.
What ions are present cesium carbonate?
The ionization of cesium carbonate: Cs2(CO3) -> 2Cs+ + CO32-. Two Cesium ions with, each with a charge of +1, and one carbonate ion, with a charge of 2-.
