Why the radius of an atom larger than the radius a positive ion formed from it?
The positive ion lost an electron.
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.
How many electrons are in a calcium atom and in a calcium ion?
A calcium atom has 20 electrons, as it has 20 protons to maintain a neutral charge. A calcium ion, specifically Ca2+, has lost two electrons, so it has 18 electrons.
What is the smallest particle of calcium that has the same chemical properties of calcium?
The smallest particle of calcium that retains the chemical properties of calcium is the calcium ion (Ca2+). This ion has lost two electrons from a calcium atom, giving it a positive charge while maintaining the chemical characteristics of calcium.
What atom has higher atomic radius Na or Na plus?
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
Arrange the following in order increasing ionic radius potassium ion sulfide ion chloride ion calcium ion?
The correct order from smallest to largest ionic radius is chloride ion < sulfide ion < potassium ion < calcium ion.
What is the name of the ion formed by a calcium atom?
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
To form an ion what does a calcium atom gain or loose?
A calcium atom typically loses two electrons to form a calcium ion with a 2+ charge. The loss of these electrons allows the calcium ion to achieve a stable electron configuration similar to that of a noble gas.
Why the radius of an atom larger than the radius a positive ion formed from it?
The positive ion lost an electron.
What is going to happen to the size of a positive ion as compared to the original atom?
The positive ion has donated an electron to another atom making the other atom a negative ion and much larger in radius. The positive ion is now much smaller in radius.
When an atom of chlorine forms an ionic bond with an atom of sodium does the atom of chlorine become an ion with a smaller or larger radius than the atom of chlorine?
The chlorine atom becomes an ion with a larger radius when it forms an ionic bond with sodium. This is because it gains an electron and becomes a negatively charged ion, causing the electron cloud to expand.
How many electrons does the calcium ion lose from an atom?
A calcium ion (Ca2+) loses two electrons from an atom to achieve a stable octet electron configuration. This results in a +2 charge on the calcium ion.
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.
How many electrons are in a calcium atom and in a calcium ion?
A calcium atom has 20 electrons, as it has 20 protons to maintain a neutral charge. A calcium ion, specifically Ca2+, has lost two electrons, so it has 18 electrons.

The smallest particle of calcium that retains the chemical properties of calcium is the calcium ion (Ca2+). This ion has lost two electrons from a calcium atom, giving it a positive charge while maintaining the chemical characteristics of calcium.
What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
When a calcium atom reacts with an oxygen atom, the calcium atom loses two electrons from its outer shell and the oxygen atom gains those electrons. This forms a calcium ion with a 2+ charge and an oxygen ion with a 2- charge. These ions then bond together to form calcium oxide.
Compare the size of the radius of a negative ion to its neutral atom?
The size of the Radius of a positve ion is smaller than a neutral atom because the postive ion has lost electrons, which means the outer most shell might be lost as well making the positve ion smaller and the nuetral atom remains the same
