List 10 UNIQUE types of metal. Example: Iron

 

Hint: Do not underestimate the easy ones.

iron, copper, aluminum, silver, gold, tin, zinc, titanium, nickel, lead.

 

isnt like 75% of the periodic table metals?

 

am i missing something here?

I know that is what I am confused about. I guess if I choose one and another person chooses the same, neither of us get a point. So I chose:

 

Praseodymium

neodymium

promethium

samarium

europium

gadolinium

terbium

dysprosium

holmium

erbium

 

Hoping no one else will choose these. There are 6 people in the group so 60 have to be chosen and there are waht like 90 some or almost 100 so I don't know. Ah well.

hi meghamann, I am curious where this problem came from and what it means for a type of metal to be UNIQUE.

 

what is a unique type of metal?

why is Iron an example of a unique type of metal?

I am clearly missing something. maybe some more explanation?

yeah it is pretty vague and does it include alloys cause then it would run into the thousands and millions of possible "unique" metals

must not forget Mercury and Platinum, also lead hey

I would assume that it would mean metals which don't share similar chemical properties. (Like sodium and potassium do). So I'll give a go with the following:

 

Sodium

Mercury

Platinum

Bismuth

Indium

Gallium

Beryllium

Copper

Neodymium

Tantalum

 

I would consider those 10 UNIQUE metals as they have different chemical and/or physical properties from each other.

how about a selection of Transition elements (including Iron) as many of them make pretty colors when salts, each one being different.
