What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
What is the relationship between the radius of a anion and that of the atom from which it is formed?
An anion is formed by gaining electrons, leading to an increase in the electron cloud's size compared to the original atom. This enlargement results in the anion having a larger ionic radius than the neutral atom from which it originated.
When an atom becomes a cation what happens to it's radius?
When an atom becomes a cation, it loses one or more electrons, causing the outermost electron shell to contract. This contraction of the electron cloud results in a decrease in the atomic radius of the cation compared to the neutral atom.
Why are the ionic radii of positive ions smaller than their corresponding atomic radii?
Positive ions have lost electrons, resulting in fewer electron-electron repulsions within the electron cloud, causing it to shrink. This leads to a smaller ionic radius compared to the corresponding neutral atom.
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
Why is the radius of anion more than the corresponding atom?
An anion has more electrons than a neutral atom.
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
How does the radius of the electron cloud compare to the radius of the nucleus?
It is about 100,000 times larger
How do the the radius and diameter of a circle compare?
The diameter of a circle is twice its radius
What is the length of an arc corresponding to an angle of one radians?
Equal to the length of the radius.

How does the length of the diameter of a circle compare to the length of the radius of that circle?
diameter = 2 X radius
How does the size of a cation compare with the size of the neutral atom from which it is formed?
An ion is an atom that carries a charge because it has more or less electrons than its neutral form. An electron weighs less than 0.06% of a proton and doesn't take up any real space, therefore an ion is not different in size than its neutral atom.
Does Na plus Na K or K plus have the largest radius?
The neutral atom of potassium has the largest radius.
