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.

Is the atomic radius of potassium larger than of calcium?
Yes, the atomic radius of potassium is larger than that of calcium. This is due to potassium having one more electron shell than calcium, leading to a larger atomic radius.
Which is larger a hydrogen atom or francium atom?
A francium atom is larger than a hydrogen atom. This is because francium has more electrons and protons in its nucleus, leading to a larger atomic size compared to hydrogen.
An atom of scandium is larger or smaller than an atom of titanium?
An atom of scandium is larger than an atom of titanium. This is because scandium has a larger atomic radius due to having more electron shells compared to titanium.
What one is larger a chlorine atom or a chloride ion?
A chloride ion is larger than a chlorine atom because it has gained an electron, leading to increased electron-electron repulsion and a larger ionic radius compared to the atomic radius of a chlorine atom.
When electron transfer results in an ion larger than the original atom?
When electron transfer results in an ion larger than the original atom, it is likely that an anion has formed. This occurs when an atom gains electrons and becomes negatively charged. The additional electrons increase the electron cloud size, making the ion larger than the original atom.
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.
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.
Which has a larger raduis calcium or copper?
Calcium has a larger radius (not raduis) than copper.
What is larger then an atom?
pretty much everything is larger than an atom.
Is a sodium atom is larger than a silicon atom?
No, a silicon atom is larger than a sodium atom. This is because silicon has more electrons and protons than sodium, leading to a larger atomic radius.
Is the atomic radius of potassium larger than of calcium?
Yes, the atomic radius of potassium is larger than that of calcium. This is due to potassium having one more electron shell than calcium, leading to a larger atomic radius.
Is molecule larger or smaller than an atom?
Larger.
Which is larger a hydrogen atom or francium atom?
A francium atom is larger than a hydrogen atom. This is because francium has more electrons and protons in its nucleus, leading to a larger atomic size compared to hydrogen.
How many atoms are larger than Ca and in the same period as Ca?
There are 17 elements larger than calcium (Ca) on the periodic table in calcium's period.
Is the model of an atom smaller or larger than the actual atom itself?
The model of an atom is larger than the actual atom itself. Atom models are simplified representations used to help understand the structure and behavior of atoms at a scale that is easier for us to comprehend.
An atom of scandium is larger or smaller than an atom of titanium?
An atom of scandium is larger than an atom of titanium. This is because scandium has a larger atomic radius due to having more electron shells compared to titanium.
