Due to smaller size of arsenic
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.
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.
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.
No, potassium and cesium are not the same. They are different elements with distinct properties. While both belong to the alkali metal group on the periodic table, cesium is larger and heavier than potassium.
Se should have a larger ionization energy than Br. This is because Se, located in the higher period on the periodic table, has a larger atomic radius compared to Br. As you move across a period from left to right, the ionization energy generally increases due to increased effective nuclear charge.
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.

Ionization energy is the energy required to remove an electron from a gaseous atom or ion. The element with the highest ionization energy is helium (He), due to its small atomic size and strong nuclear charge. In contrast, cesium (Cs) has one of the lowest ionization energies, as its larger atomic radius and increased electron shielding make it easier to remove an outer electron.
Cesium (Cs) is more reactive than strontium (Sr). Both elements belong to the alkali and alkaline earth metal groups, respectively, but cesium is located further down the periodic table, which increases its reactivity due to its larger atomic radius and lower ionization energy. This makes cesium more likely to lose its outer electron and participate in chemical reactions.
Cesium will have a larger atomic radius than magnesium. This is because atomic radius tends to increase down a group in the periodic table, and cesium is located below magnesium in the periodic table.
An arsenide ion is larger than a bromide ion, but a bromide ion is larger than an arsenic ion. Recall that arsenic can have several oxidation states. It can be a cation or an anion.
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.
No, potassium and cesium are not the same. They are different elements with distinct properties. While both belong to the alkali metal group on the periodic table, cesium is larger and heavier than potassium.
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.
In Group 1 of the periodic table, the strength of bases generally increases as you move down the group. This is because the alkali metals (lithium, sodium, potassium, rubidium, cesium, and francium) become more reactive and their hydroxides become stronger bases as the size of the metal cation increases. Among them, cesium hydroxide (CsOH) is typically considered the strongest base due to cesium's larger atomic size and lower ionization energy compared to the other alkali metals.
