Europium | Chemistry

E.S. Infante d. Henrique, Porto, Portugal

Europium: Europium is the chemical element with atomic number 63. Discovered in Europe, led us to illustrate the map of Europe. The patron of our school is Infante D. Henrique who in the sixteenth century promoted the discovery that gave new worlds to the World. Our school is located in Porto, a coastal city in the extreme southwest of Europe (as indicated by the red pin in the picture). To style the chemical symbol we adopted the astrolabe, an instrument used to assist the navigation by the Portuguese navy. We drew nuclear reactors since europium acts as a neutron scavenger and therefore is used in nuclear reactor control rods.
