Ionic bonds
Is the following an Ionic bond? if not, what bond is it?
BN
No, its covalent
What makes a covalent bond?
2 nonmetals bonding
What is a metallic bond?
A metallic bond is a bond that consists of 2 metals
Name any prefix
Mono, di, tri, tetra, penta, hexa, hepta, octo, nona, deca
Is the following an ionic bond? / BaBr2
Yes
What happens to electrons when a covalent bond occurs?
They are shared
In what way do electrons move in this type of bond?
freely
What does penta mean?
What happens to electrons during an ionic bond?
They can be lost or gained.
Is the following a covalent bond? / NaOH
No
Why are metals good conductors of electricity and heat?
This is because unlike a bond like a covalent bond, the electrons are able to move freely, and they just have good electrical/thermal conductivity.
What is a rule for naming ionic bonds
You need to name the cation first, anion second, or if it's a polyatomic ion, name the ion.
What is the name of the following compound? / Al2S3
Aluminum sulfide
What is the name for the following compound? / PCl5
Phosphorus pentachloride
Why do metallic bonds typically have high melting points?
This is because a lot of heat/energy is required to separate the strong bonds from each other, and metals have high melting points themselves.
how would you name a metal?
you would name it by its element name, ex. Fe=Iron or Ag=silver
How do ionic bond physical properties differ from covalent bonds?
Some things they differ in are melting/boiling points, solubility, electrical conductivity, malleability/brittleness, and hardness
Why do nonmetals tend to form covalent bonds instead of ionic bonds?
High electronegativity and atomic structure make covalent bonds more common than ionic.
What is an example of a metallic compound?
give a name, the compound equation thing, and explain why it's a metallic bond
Any metallic bond the tester names with the requirements
How would you name a covalent bond?
give a more detailed answer of the steps you would thing that you would use.
You would name the first element fully then use a prefix on the second, unless you need to use a prefix on the first element.
