2 Bonding 1 Flashcards
What charge will an ion of lithium take?
1+ (one electron in the outer shell, needs to lose it)
What charge will an ion of beryllium take?
2+ (two electrons in the outer shell, needs to lose them both)
What charge will an ion of fluorine take?
1- (7 electrons in the outer shell, needs to gain one)
If an atom has gained electrons, what charge will it have?
Negative
If an has lost electrons, what charge will it have?
Positive (because they have lost an electron/s)
What charge will an ion of oxygen carry?
2- (6 electrons in outer shell so needs to gain two)
Explain in terms of electrons what occurs when lithium bonds with chlorine
One electron transferred from lithium to chlorine
Why do atoms transfer electrons in ionic bonding?
So that they can have full outer shells
Explain in terms of electrons what occurs when lithium bonds with fluorine
One electron transferred from lithium to fluorine
Explain in terms of electrons what occurs when magnesium bonds with oxygen
Two electrons transferred from magnesium to oxygen
Explain in terms of electrons what occurs when magnesium bonds with chlorine
One electron transferred from magnesium to two different chlorine atoms
Explain in terms of electrons what occurs when sodium bonds with oxygen
Two electrons transferred to an oxygen atom from two different sodium atoms
Why do sodium ions and chlorine ions form an ionic bond?
There is an electrostatic force of attraction between the positively charged sodium ion and the negatively charged chloride ion
What is the name for a substance made of billions of oppositely charged ions joined together?
Giant ionic lattice
Define giant ionic lattice
A huge 3D network of ions
