Topic 2 - Ionic Bonding Flashcards
(18 cards)
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
what is the charge of Ag?
1+
what is the charge of Cu?
2+
what is the charge of Pb?
2+
what is the charge of Zn?
2+
what is the charge of Hydroxide (OH)?
1-
what is the charge of Ammonium (NH)?
1+
what is the charge of Carbonate(CO3)?
2-
what is the charge of Nitrate(NO3)?
1-
what is the charge of Sulfate(SO4)?
2-
what is the charge of H?
1+
what happens when a metal and non-metal react?
the metal ion loses electrons and the non-metal gains electrons
what is an ionic bond?
oppositely charged ions are strongly attracted by electrostatic attractions
