Ionic Bonding Flashcards
What do atoms have to do for them to become ions?
Either lose electron(s) or gain electron(s).
An electron is a ________ particle.
Charged.
An atom whose outer shell requires 1 electron will be keen to do what?
Gain an electron and become a negatively charged ion.
An atoms whose outer shell contains 1 electron will be keen to do what?
Lose that electron and become a positively charged ion.
Which group of elements are keen to become positively charged ions by losing an electron or two?
Group 1 & 2 atoms, the left-hand side of the periodic table.
Which group of elements are keen to become negatively charged ions by gaining an electron or two?
Group 6 & 7 atoms, the right-hand side of the periodic table.
What are the Group 8 elements? Why do all atoms aspire to be like them structurally?
They are the Noble Gases and they have a full outer shell of electrons, everyone wants to be them, they’re like the Regina Georges of the periodic table.
Ionic compounds have which structure?
A regular lattice structure.
What is a regular lattice structure?
A giant lattice structure, the ions are packed together very tightly together and they forces of electrostatic attraction between these ions are VERY strong.
What effect does an ionic lattice’s strong forces of electrostatic attraction have on its boiling and melting points?
Very high boiling points and very high melting points. This is because the forces between the ions require a lot of energy to be broken, they’re tough as FUCK.
What happens to the ions of an ionic lattice when it melts?
They’re free to move about and carry electric current.
Do ionic compounds dissolve easily in water?
Yes. The ions separate and are all free to move around in the solution, they carry current, making them perf for electrolysis 😩👌🏼😭
