Period Number of Thallium (Tl) (& Location, Uses ...

All atoms have a period number assigned, even Thallium. Ok but how do we know what is the period name for an atom of Tl?

If we know the symbol, let's say Tl, we may then open any periodic table and search for Thallium. Any decent periodic table should have the period numbers when you scroll left starting from the element you found.

In the case of Thallium the period number is 6. There is a lot of cool stuff about Thallium that people simply don't know. Let me show you...

solid

Description

Soft gray metal that looks like lead.

Atomic Symbol

Tl

Name Origin

Greek: thallos (green twig), for a bright green line in its spectrum.

Sources

Found in iron pyrites. Also in crookesite, hutchinsonite and lorandite. Most is recovered from the byproducts of lead and zinc refining.

Uses

Its compounds are used in rat and ant poisons. Also for detecting infrared radiation.

Citation

When you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.

That gives credibility to your paper and it is sometimes required in higher education.

To make your life (and citation) easier just copy & paste the information below into your assignment or essay:

Luz, Gelson. "Period Number of Thallium (Tl) (& Location, Uses ..." Materials. Gelsonluz.com. dd mmmm. yyyy. <URL>

Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
