Ionic Bonding Flashcards
Why do element react with each other?
Elements react with each other to get a full outer shell, achieving stabilityby having an electronic structure of a noble gas.
What two types of elements need to react with each other for it to be ionic bonding?
A metal needs to react with a non metal.
When an atom loses an electron…
… it forms a positive ion (it is positively charged).
When an atom gains an electron…
… it forms a negative ion (it is negatively charged).
Group 1
Loses 1 electron, + ion.
Group 2
Loses 2 electrons, 2+ ion.
Group 3
Loses 3 electrons, 3+ ion.
Group 5
Gains 3 electrons, 3- ion.
Group 6
Gains 2 electrons, 2- ion.
Group 7
Gains 1 electron, - ion.
