What else can I help you with?
Is strontium larger than a calcium atom?
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.
What has greater atomic size calcium or strontium?
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.
What elements are more reactive than lead?
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.
Are magnesium and calcium more reactive with oxygen in the air than is aluminum?
Yes, both magnesium and calcium are more reactive with oxygen in the air than aluminum. Magnesium and calcium readily form oxides when exposed to oxygen, while aluminum forms a protective oxide layer that prevents further reaction.
What is more water soluble calcium sulfate or strontium sulfate?
Calcium sulfate is more water soluble than strontium sulfate. In water, calcium sulfate has a solubility of about 0.2 g per 100 mL at room temperature, whereas strontium sulfate has a solubility of about 0.006 g per 100 mL at the same temperature.
Is beryllium more reactive than strontium?
No, strontium is more reactive than beryllium.
Why Ba is more reactive than Ca?
strontium is more reactive than calcium because it is more electropositive. valance electrons of strontium are farther away from the nucleus of strontiium atom than the valance electrons of calcium from nucleus of calcium atom. so the force exerted by the nucleus on the valence electron of strontium is lesser than that exerted by calcium. so the strontium atom can loose its valance electrons more easily. therefore strontium is more electropositive and more reactive than calcium.
Is calcium sulfide more or less reactive to aluminum?
Chemistry of calcium Calcium is generally more reactive than magnesium
Is strontium larger than a calcium atom?
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.
What is more reactive calcium or more reactive?
Calcium is more reactive but not as Potassium or Sodium because according to the displacement series Calcium comes as third and the last under the reactive elements of the displacement series.
Is calcium more reactive than aluminium?
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
What element is more active Sr or Ag?
Sr (strontium) is considerably more reactive than Ag (silver). In fact, Strontium is so reactive that it must be stored in mineral oil to prevent its reaction with the oxygen in the air. Strontium also reacts with water.
What has greater atomic size calcium or strontium?
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.
Calcium or bromine which is more reactive?
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
What elements are more reactive than lead?
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.
Are magnesium and calcium more reactive with oxygen in the air than is aluminum?
Yes, both magnesium and calcium are more reactive with oxygen in the air than aluminum. Magnesium and calcium readily form oxides when exposed to oxygen, while aluminum forms a protective oxide layer that prevents further reaction.
Which element would be most reactive be sr or ba?
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.
