The Precambrian is the earliest of the geologic ages, which are marked by different layers of sedimentary rock. Laid down over millions of years, these rock layers contain a permanent record of the Earth's past, including the fossilized remains of plants and animals buried when the sediments were formed. (P.s i read abt this in science not long ago but this is also sourced from nationalgeographic.com so it should be correct.)
Hope this helps.
The appropriate response would be Tellurium. For the reason that it can receive a - 2 charge, and when it grabs two electrons, it fills the 5p shell with six electrons, so it will have the electronic arrangement of [Xe]. It cannot be Barium since if it loses two electrons, it will get the electronic configuration of [Xe] when it loses the 6s2 electrons, but it will be a +2 cation, not an anion.
