c2 Flashcards
when are ions made?
when electrons are transferred
what are ions?
charged particles
what happens when atoms lose or gain ions?
they are trying to get a full outer shell
what happens when metals form ions?
they lose electrons in there outershell to form positive ions
what happens when non-metals form ions?
they gain electrons in there outershell to form negative ions
which groups are most likely to form ions?
1267
which groups are metals?
12
what are positive ions?
cations
what are negative ions?
anions
what groups are non-metals?
67
what happens to elements in the same groups?
they have the same number of outer electrons so they loose or gain to get full outershell
what is ionic bonding?
when a non-metal and metal ion react the metal loses elctrons to gain positive ions and the non-metal gains electrons to form negative ions , oppositely charged ions are strongly attracted by electrostatic forces.
how are ions formed?
when an atom loses or gains electrons
ionic compounds?
have a regualr lattice structure called giant ionic lattice
what are ionic compounds properties?
high melting point, dissolve in water, when solid ions stay in place
