Barium is more reactive than strontium primarily due to its larger atomic size and lower ionization energy. As you move down the alkaline earth metal group in the Periodic Table, the atomic radius increases, making it easier for the outer electrons to be removed. Barium's additional electron shell reduces the effective nuclear charge experienced by its outermost electron, facilitating its reactivity compared to strontium. Additionally, the weaker attraction between the nucleus and the outer electrons in barium enhances its tendency to lose electrons and react.
sodium because it's the first group and first group are the most
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the periodic table.
Barium is more reactive than magnesium.
In the group 2 elements, the reactivity of the metals increase as you move down the group. The order of reactivity in group 2 is barium, strontium, calcium, and magnesium.
No chromium is more reactive than chromium because it it located farther right on the periodic table than nickel. No chromium is more reactive than nickel because it it located farther right on the periodic table than nickel. No chromium is more reactive than nickel because it it located farther right on the periodic table than nickel. No chromium is more reactive than nickel because it it located farther right on the periodic table than nickel.
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
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.
sodium because it's the first group and first group are the most
Yes, because it is lower down in the group.
Barium (Ba) would be more reactive than strontium (Sr) because barium is located further down the Group 2 elements in the periodic table. As you move down the Group, the reactivity of the elements tends to increase due to the larger atomic size and lower ionization energy, making barium more reactive than strontium.
Calcium and barium have different reactivities. Barium is more reactive than calcium because it has a greater tendency to lose electrons and form positive ions in chemical reactions. Calcium is a moderately reactive metal that readily forms compounds with oxygen and water, but it is not as reactive as barium.
Fluorine would be the more reactive element because it needs to gain one electron. While Barium needs to gain two electrons. Thus it is easier to gain one than to lose two.
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the periodic table.
Barium is more reactive than magnesium.
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.
Calcium and barium have similar reactivities, because they are both alkaline earth metals. Quantitatively, barium is slightly more reactive than calcium because it has more electron shells between its valence electrons and its nucleus.
The metals listed are all alkali metals or alkali-earth metals. The periodic trend for these groups is: as you move down the group/family, reactivity increases. The alkali metals will be more reactive than the respective alkali-earth metals.Sodium and lithium are alkali metals, so you can organize them first. Sodium is further down in the family than lithium, so we can say that sodium is the most reactive out of the group, followed by lithium. Then we have barium and radium left. Radium is slightly more reactive than barium due to its position, so it is third and barium is fourth.
