Does an anion always form a covalent bond?
No. An anion may contain covalent bonds, if it is a polyatomic anion, but an anion forms only ionic bonds if the anion's chemical integrity is maintained.
When naming ionic bonds what does the anion always end in?
ide
Is PO4 a cation or an anion?
polyatomic anion
What one is larger a chlorine atom or a chloride ion?
anion is always larger than its parent atom
Which describes an anion?
An anion is an ion with a negative charge - so SO42- is an anion
Does an anion always form a covalent bond?
No. An anion may contain covalent bonds, if it is a polyatomic anion, but an anion forms only ionic bonds if the anion's chemical integrity is maintained.
Is An anion is smaller than the atom from which it is produced?
No, an anion is the atom plus extra electrons which give that atom a negative charge. The anion is thus, always bigger than the original atom.
When naming ionic bonds what does the anion always end in?
