Subject: [TN] NTC Friday Element Quiz - The Question
Hi folks - Here is the Friday Element Quiz:
The Question:
This element has been described as a "workhorse element". It is a low
melting, low stiffness metal with moderate strength. In humans, a daily
intake of 15 mg of this element is recommended. A deficiency of this
element in the human body can cause deformed fingernails and delay the
onset of puberty for several years. This element's low melting point
results in room temperature recrystalization behavior measured in seconds.
Its crystal structure is HCP. The element ranks 4th in annual production
behind Fe, Al and Cu despite it not being very abundant in the Earth
crust. What element am I?
Bonus point question: What is this element's abundance in the Earth crust
as measured in ppm?
Doug is in Florida this week so we voted to give away is stapler to the
quiz winner.
Good Luck.
