Strontium
The electronegativity of barium is less than that of strontium.
Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.
The Atlantic Ocean is larger than the Indian Ocean.

Oh, what a delightful question! Strontium has a larger atomic radius than magnesium. You see, as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of more electron shells. So, in this case, strontium, being located below magnesium on the periodic table, has a larger atomic radius.
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.
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.
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.
About twice as large, which is not that much at the first ionization level. Still, Magnesium has a slightly larger, one proton nucleus and one more electron in that valence level to add to the energy needed to pill the first electron out of it's orbital. Electron shielding may have something to do with this also as the other valance electron of this 2+ element may shield the pulled electron.
Strontium has a greater atomic size than calcium because strontium has more electrons and energy levels in its electron cloud, resulting in a larger atomic radius.
Yes, strontium is larger than a calcium atom. Strontium has a higher atomic number (38) compared to calcium (20), which means it has more electron shells. This additional shell increases the size of the strontium atom, resulting in a larger atomic radius than that of calcium.
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.
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
An element that has a larger ionic radius than calcium is strontium. Strontium is located below calcium in the same group of the periodic table, which means it has an extra energy level and therefore a larger ionic radius.
Atoms do not have a radius. A helium atom has a nucleus composed of at least two protons and maybe one or two neutrons. A magnesium atom nucleus (and every other atom on the periodic table other than hydrogen) is BIGGER than a helium nucleus. So if you look at it that way...magnesium is larger than helium
Barium is the largest alkaline earth metal due to its larger atomic size compared to the other alkaline earth metals like magnesium, calcium, strontium, and radium.
