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 else can I help you with?
Is calcium more reactive than strontium?
No, strontium is more reactive than calcium. This is because strontium is located below calcium in the periodic table and thus has a larger atomic size, making it easier for strontium to lose its outermost electron and react with other elements.
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.
Why is it easier for strontium to lose valence electrons than calcium?
Strontium is larger in size compared to calcium due to more electron shells, making it easier for strontium to lose valence electrons farther from the nucleus. This results in weaker attraction between the valence electrons and the nucleus, leading to easier electron loss in strontium compared to calcium.
Which one has the larger radius strontium atom or an iodine atom?
Strontium has a larger atomic radius than iodine. This is because strontium is located in Group 2 of the periodic table and is a metal, while iodine is a nonmetal found in Group 17. As you move down the periodic table, the atomic radius increases due to the addition of electron shells, and strontium, being lower in the table, has more electron shells than iodine.
Calcium magnesium and strontium are near each other on the periodic table and have some characteristics in common but they differ in chemical reactivity. Which lists these metals in order from most re?
The order of calcium, magnesium, and strontium from most reactive to least reactive is strontium, calcium, and then magnesium. Strontium is more reactive than calcium due to its lower ionization energy and larger atomic radius, which make it easier to lose electrons. Magnesium, while still reactive, is less so compared to both strontium and calcium because of its higher ionization energy.
Is calcium more reactive than strontium?
No, strontium is more reactive than calcium. This is because strontium is located below calcium in the periodic table and thus has a larger atomic size, making it easier for strontium to lose its outermost electron and react with other elements.
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.
Why is it easier for strontium to lose valence electrons than calcium?
Strontium is larger in size compared to calcium due to more electron shells, making it easier for strontium to lose valence electrons farther from the nucleus. This results in weaker attraction between the valence electrons and the nucleus, leading to easier electron loss in strontium compared to calcium.
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.
Which element has a larger ionic radius than calcium?
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.
Calcium magnesium and strontium are near each other on the periodic table and have some characteristics in common but they differ in chemical reactivity. Which lists these metals in order from most re?
The order of calcium, magnesium, and strontium from most reactive to least reactive is strontium, calcium, and then magnesium. Strontium is more reactive than calcium due to its lower ionization energy and larger atomic radius, which make it easier to lose electrons. Magnesium, while still reactive, is less so compared to both strontium and calcium because of its higher ionization energy.
A calcium atom is larger than a calcium ion because?
a calcium atom is larger because it contains more electrons than a calcium ion. When a calcium atom loses electrons to become a calcium ion, it becomes smaller due to the loss of electron-electron repulsion, causing the remaining electrons to be pulled closer to the nucleus, resulting in a smaller size.
Who has the largest radius calcium atom or calcium ion?
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.
Is the electronegativiy of barium larger or smaller than that of strontium?
The electronegativity of barium is less than that of strontium.
Is a calcium atom larger than a barrium atom?
Calcium contains 20 protons, 20 neutrons and 20 electrons (on average). Barium has 56 protons 81 neutrons and 56 electrons (again, on average). So, Barium is much larger.
How is a strontium atom different from a strontium ion?
An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.
Which is more reactive Mg or Ca Why?
Calcium is more reactive. In the periodic table, Calcium is directly below Magnesium, which means that a calcium atom is larger than a magnesium atom. This means that the electrostatic attraction between the valence electrons of calcium and the nucleus is weaker than in magnesium(larger distance, smaller force). So, the valence electrons of calcium can easily be lost to form Ca2+ , which translates to Calcium being the more reactive metal.
