Topic 2 - Ionic Bonding Flashcards
how are anions formed?
atoms gain electrons so become negatively charged
how are cations formed?
atoms lose electrons so become positively charged
if an atom lost 2 electrons what would its charge be?
2+
which groups lose electrons in ionic bonding?
1,2 and 3
which groups gain electrons in ionic bonding?
5,6 and 7
do elements in the same group form ions with the same charge?
yes, because they have the same amount of electrons in their outer shell, so lose/gain the same amount of electrons
