Cerium Cerium is a soft, ductile, silvery-white metallic chemical element with symbol Ce and atomic number 58. Cerium tarnishes when exposed to air, and it is soft enough to be cut with a knife. Cerium is the second element in the lanthanide series, and while it often shows the +3 state characteristic of the series, it also exceptionally has a stable +4 state that does not oxidise water.

- BCE = Before Common Era. CE = Common Era. These two abbreviations have been used as replacements for B.C. and A.D. Something I find funny is that while these abbreviations have been chosen as non religious alternatives, one could use the word BCE to mean, Before Christian Era, and CE to mean Christian Era. #bc#ad#bce#ce#history#religion#christianity.

Capricorn symbol The Capricorn symbol (also called Capricorn glyph) is a shorthand representation of the Capricorn zodiac animal (see below).However, as with the animal itself, much is based both in interpretation and the preference of the writer, and can range from simple to extravagant.ue to this although Capricorn will always be represented by a (sea)goat, there isn't any one 'correct' shape or design for that goat. It's a cosmic game of join the dots, and some constellations even have alternative ways to form the animal from the dots (stars).
