Question

Tell weath each is an example of Ionic, Covalent, or Metallic

1) Salts- metal & nonmetal
2) malleable, ductile, lustrous, conductive
3) odorous

Answer 1

Ionic, Covalent and Metallic are all types of chemical bond (or atomic bond)

So which of the answers lists types chemicals that might have different the types of bond in the question?

Answer 2

*the different types

I swear I can't type today

Answer 3

it wants me to match each of the 123 examples with a diffrent bond

Answer 4

Oh, right, I misread the question

Do you have an idea of what each of the types of bond are?

Answer 5

my best guess would be
1. Metallic
2. Covalent
3. Ionic

Answer 6

1) says metal and non-metal and metallic bonds occur in metals only

2)
"malleable" means can be hammered or pressed into shape without breaking
"ductile" means you can draw it out into a wire
"lustrous" means shiny
"conductive" means heat and/or electricity pass through it

3)
well.. "odorous" means it smells

Let's define ionic and covalent:

Ionic bonds occur when atoms have more or fewer electrons than protons so they become charged ions. What causes this is that it's energetically favourable for atoms to have full outer shells of electrons, so if you have an atom (like Sodium) with 1 electron in its outer shell another atom (like Chlorine) with 7 electrons in its outer shell (which can take 8) then the outer electron from the Sodium will go to the Chlorine atom. This means they both have full outer shells and the Sodium will have a positive charge and the Chlorine will have a negative charge, so they attract each other. Sodium chloride is normal table salt.

Covalent bonds are when atoms share (rather than give/take) outer electrons to make full shells. Oxygen has 6 outer electrons of a possible 8, so you can think of it as 6 electrons and 2 gaps. Two oxygen atoms will bond covalently to make oxygen gas \(O_2\) by sharing two electrons from each atom

Answer 7

okay, so is #1 Ionic?

Answer 8

Yep

Answer 9

Is 2 Convalent?

Answer 10

No, 2 describes something that can be hammered in to shape, drawn into a wire, is shiny and conducts heat/electricity.
Sounds like a metal to me

Answer 11

Oh! okay, well then why is 'odorous' convealent?

Answer 12

Not every chemical held together by covalent bonds has an odour. Carbon dioxide, oxygen, hydrogen, helium don't smell at all.

But, for example, sulphur dioxide is held together covalently and that smells of rotten eggs.
Gasoline, alcohol, benzyl acetate (the chemical that makes strawberries smell like strawberries) all have covalent bonds

Answer 13

oh okay! thank you so much! That really explaned it :)
