What is a lanthanide metal named after a continent?
Europium (Eu)
What lanthanide forms a compound that allows you to see red on a computer screen?
The color red appears on a computer monitor because of a compound formed from europium that coats the back of the screen.
What does the element Europium bond with?
Europium is a lanthanide. It forms oxides halides a sulfide and other compounds. It forms salts such as europium(III) sulfate. It is quite reactive and needs to be stored without contact with air as it readily oxidises.
Zr and Hf almost show same chemical properties?
Due to lanthanide contraction
Why does osmium has the greatest density?
Osmium has the greatest density (of any stable element) - this is due to Lanthanide Contraction, where poor shielding of nuclear charge results in decreased atomic radius.
What family is europium in?
The chemical element of Europium is part of the lanthanide series. The lanthanide series is comprised of metallic elements, these can be referred to as rare earth elements.
What is a lanthanide metal named after a continent?

Is europium a solid liquid or gas?
no. it is a metal and a f block element (a lanthanide)
Which lanthanide forms a compound that enables you to se red on a computer screen?

What is the state of matter of europium?
Europium is solid at room temperature, as are all metals with the exception of mercury.
What element has 63 electrons?
Iodine (I) has 53 electrons; the number of electrons is identical to number of protons and the atomic number.
What are cerium and europium examples of?
One of the examples of cerium is a lighter flint and a fire starter.
Zr and Hf almost show same chemical properties?
Due to lanthanide contraction
Europium?
A silvery-white metal of the lanthanide series that reacts readily with air to form a dark oxide coating. It is the most chemically reactive, least dense, and softest of the lanthanide elements. It is one of the rarest of the rare-earth elements on Earth and has no significant biological role.
