Ionic Bonding
What elements form ionic bonds?
Metal and non-metal elements form ionic bonds.
What is a molecule?
A group of atoms held together by a covelant bond.
How do metallic bonds conduct electricity with metals?
Metallic bonds have free-moving electrons, which can flow and carry and electric current.
What is Fe2O3 trasnlate to?
Iron (III) oxide.
What is the rule that shows whether a bond is ionic?
If the bond has a large difference with electronegativity between the atmos.
What happens to the electrons in a covalent bond?
They are shared between atoms.
How does metallic bonding interact with thermal conductivity?
It allows metals to conduct heat easily by mkaing energy trasnfer through the electrons.
What ions ends with "-ate"
Sulfate, Nitrate, Phosphate etc.
Why do ionic bonds have high melting and boiling points?
Ionic compounds have a strong electrostatic force between the ions, requiring a large amount of energy to break up the bonds.
Why do covalent bonds not conduct electricity?
Covalent bonds do not have free-moving ions to conduct electricity.
Are metallic bonds brittle or malleable? Why?
Metallic bonds are malleable. This is because metal ions pass by each other without breaking the bond.
What does the prefix "di-" mean?
It is a prefix used to show two of the same atoms.
Why are ionic bonds conductive when dissolved in water?
The compounds separate into ions, causing them to be conductive.
Why do covalent bonds usually bond with non-metals?
Non-metals share electrons with their outer shell.
What happens to electrons in a metallic bond?
The electrons move freely and are not shared between the atoms.
How many nitrogen and oxygen is in Dinitrogen Tetroxide?
Two nitrogen and four oxygen atoms.
How does electron transfer work in an ionic bond?
One atom gives electrons to another, creating a positive and negative ion that attract each other.
What is a polar covalent bond?
It is a bond which the electrons are shared unevenly, causing a charge difference.
Why do metlas have high melting and boiling points?
The strong attarctions between the metal cations and electrons require a lot of energy to break them.
