Period Number of Selenium (Se) (& Location, Uses ... 2022

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

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

In the case of Selenium the period number is 4. There is a lot of cool stuff about Selenium that people simply don't know. Let me show you...

Discovery

Discovered By: Jöns Berzelius
Year: 1818
Location: Sweden

State at 20 °C

Solid

Description

Soft metalloid similar to sulfur. Ranges from gray metallic to red glassy appearance.

Atomic Symbol

Se

Name Origin

Greek: selênê (moon).

Sources

Obtained from lead, copper and nickel refining. Conducts electricity when struck by light.

Uses

Light causes it to conduct electricity more easily. It is used in photoelectric cells, TV cameras, xerography machines and as a semiconductor in solar batteries and rectifiers. Also colors glass red.

Colored Periodic Table

Need an editable periodic table to edit? Maybe add your school logo, work team or anything else to maker your paper look cool?

Along with basic atom / element information (like Selenium period number and all the other atomic data), it also comes with color coded info about: State (Gas, Liquid or Solid at room temperature), Groups/series details and much more...

How about an incentive to share this post? (You will help other colleagues find this blog)

Download and enjoy this complete and colored periodic table for you to edit and enjoy. It's in an editable excel format or .ods (open).

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 Selenium (Se) (& 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.
