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 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.


Are cations bigger than anions in terms of size?

In general, cations are smaller than anions in terms of size.


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


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.


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.


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 anions have a larger radius compared to cations?

Yes, anions have a larger radius compared to cations.


Do anions and cations share electrons during ionic bonding?

No, anions and cations do not share electrons during ionic bonding. In ionic bonding, cations lose electrons to anions, resulting in the formation of an ionic bond based on electrostatic attraction between the positively and negatively charged ions.


What is the general word for both cations and anions?

The term "ion" can be used to refer to both anions and cations.


Cations and anions similar?

No, cations have a positive charge and have lost electrons. Anions have a negative charge and have gained electrons. In an ionic compound anions and cations attract each other due to opposite charges.
