Why are size of cations always smaller and size of anions always bigger than the corresponding atom?

anions always gain extra electrons casing the ionic radius to increase but cations remove electrons causing the ionic radius to decrease .therefore anionic radius is greater than cationic radius

How do you tell apart cations and anions?
cations, positively charged ions, can be told from anions, negatively charged ions, bysize--cations are smaller then the average atomic mass of the element --anions are largertype--cations are made from metals --anions are non-metalsorder--cations are always listed first in a chemical equation
O2- is larger than O?
Yes, because anions are always bigger than the atom in its ground state. Cations are smaller
A anions and xenons b anions and cations c cations and xenons d xenons and anions Which of these are ions?
The ions are b, anions and cations. Note that xenon is not an ion, it is a noble gas.
Do anions and cations share electrons during ionic bonding?
Yes anions and cations share electrons. Anions gain electrons and cations loose electrons.
Will polonium make cations or anions?
cations
How do the sizes of cations and anions relate to the atoms they form from?
Cations are formed when atoms lose electrons and hence are smaller in size than the corresponding atoms. Anions are formed when atoms gain electrons and hence are larger in size than the corresponding atoms.

What conclusions can we make about the size of cations neutral atoms and anions?
Cations are smaller then neutral atoms and anions are larger.

Yes, because anions are always bigger than the atom in its ground state. Cations are smaller

Yes anions and cations share electrons. Anions gain electrons and cations loose electrons.
How do you know if a cation is positive or negative?
Cations are always positive, anions are negative.
Are anions and cations ion?
Yes. Anions are negative ions and cations are positive ions.
Which tool would be used to find information on which cations or anions will replace other cations or anions in a chemical reaction?
A displacement table would be used to find information on which cations or anions will replace other cations or anions in a chemical reaction.
Will polonium make cations or anions?
cations
What are smaller cations or anions?
cations are smaller than the atoms from which they were formed because they lost an electron thus becoming smaller in size. anions are bigger than the atoms from which they were formed because they gained an electron and increasing in size. the greater the nuclear charge, the smaller they are.

Do alkali metals generally make anions or cations?
Cations.
