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.

What conclusions can we make about the size of cations neutral atoms and anions?
Cations are smaller then neutral atoms and anions are larger.
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.
Do alkali metals generally make anions or cations?
Cations.
Which tool would be used to find info on which cations or anions will replace other cations or anions in a chemical reaction?
a reactivity series
Which tool would be used to find information on which cations or anions will replace othe cations or anions in a chemical reaction?
A tool that would be used to find information on which cations or anions will replace others in a chemical reaction is a displacement table.
What conclusions can we make about the size of cations neutral atoms and anions?
Cations are smaller then neutral atoms and anions are larger.
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
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.
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
Do alkali metals generally make anions or cations?
Cations.
What is the general word for both cations and anions?
The term "ion" can be used to refer to both anions and cations.
Are oxide ions cations or anions?
anions oxides are O2-
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.
Why cationic molecular ions are greater then anionic one?
It is wrong. Cations are smaller than ions. It is because when cations are formed the outer shell of the element is removed but this does not happen with anions.
