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.
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.
Barium is smaller than caesium. Different elements have different atomic radii, with caesium having a larger atomic radius compared to barium.
Sulfur has a larger atomic radius than magnesium. This is because as you move down a group in the periodic table, atomic radius increases due to the addition of more electron shells. Magnesium is higher up in the periodic table than sulfur, so it has a smaller atomic radius.
Cesium has a larger atomic radius than rubidium. This is because as you move down a group in the periodic table, the atomic radius generally increases due to the addition of more energy levels and electrons.
Element M is likely calcium. It is more reactive than magnesium and has a smaller radius than barium, making it a good fit for the given properties. Calcium forms a compound MCl2 when reacting with chlorine.
Bromine has a larger atomic radius than magnesium. Atomic radius generally increases as you move down a group on the periodic table, so bromine, being below magnesium, has a larger atomic radius.
Carbon vs. Oxygen: Oxygen has atoms with a larger atomic mass. Sodium vs. Magnesium: Magnesium has atoms with a larger atomic mass. Phosphorus vs. Sulfur: Sulfur has atoms with a larger atomic mass.
Cs (Cesium) is the largest element among Li (Lithium), K (Potassium), and Cs (Cesium) due to having the highest atomic number and larger atomic radius.
Strontium
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.
Barium is smaller than caesium. Different elements have different atomic radii, with caesium having a larger atomic radius compared to barium.
Sulfur has a larger atomic radius than magnesium. This is because as you move down a group in the periodic table, atomic radius increases due to the addition of more electron shells. Magnesium is higher up in the periodic table than sulfur, so it has a smaller atomic radius.
Francium has a larger atomic radius than cesium as you move down the periodic table within the same group. This is because as you move down a group, the number of energy levels or shells increases, leading to a larger atomic radius. Therefore, Francium, being further down Group 1, has a larger atomic radius compared to cesium.
Strontium has a larger atomic radius than magnesium. This is because atomic radius generally increases down a group in the periodic table. Strontium is located below magnesium in the same group (group 2), so it has more electron shells and a larger atomic radius.
No, magnesium has a larger atomic radius than helium. Magnesium is a metallic element with more electron shells and therefore a larger atomic radius compared to helium, which is a noble gas with a smaller atomic radius.
Barium has a larger atomic radius than tin.
Potassium is larger than magnesium because potassium has one more electron shell than magnesium, leading to a larger atomic size. Additionally, the increase in nuclear charge from magnesium to potassium is not enough to offset the added electron shell, resulting in a larger atomic radius for potassium.
