Magnesium. According to GLaDOS, at least.
Because in portal 2 Caroline's "mind" was inserted. But in portal 1 it wasn't
GLaDOS Genetic Lifeform and Disk Operating System I'd say her real name but it would ruin the surprise.
Portal is an interacting game where teens and young adults can travel through test, using science! Portal 3 is including 'Atles' and 'Pbodies' adventures through space, and solving test for GLaDOS, but the bad news is, Wheatly's returned It turns out, when Test Subject pulled him out of space, Wheatly landed on earth through Test Subjects imansipation grid. He now searches for GLaDOS in order to control over her test(s) and most importantly, revenge for calling him a 'moron'. Its up to Atlas and Pbody to save GLaDOS and try to kill Wheatly, once and for all. 12/9/12
GLaDOS is different in Portal 2 because she is in another body. We know there are multiple GLaDOS chassis because in the comic there are multiple GLaDOS prototypes and in the games she activates multiple cores, is put in to the POTaTOS body and tells the robots P-Body and ATLAS that there is an intruder in one of her old chassis and forces them to confront it. However her new body is and old prototype and has very limited power over the facility and in the multiplayer function the robots put discs into the GLaDOS mainframe and restore her to full power. The way the prototype body got down to the GLaDOS control room is decaying walls and floors that crumble over the decades allowing the body to drop in.

Escaping the psychopathic clutches of GLaDOS.
GLaDOS stands for.......(Genetic Lifeform and Disk Operating System) GLaDOS is the sentient computer system that manages Aperture Laboratories is Portal. She is the antagonist throughout Portal 1 and the first part of Portal 2.
Glados
GlaDOS was such a beloved villain in Portal because he was obsessed with cake and very passive-aggressive. This made him funny and charming.
Magnesium. According to GLaDOS, at least.
he goes crazy, alot like GLaDOS in portal 1
She offers it as a reward in the course of the game. During the ending credits a cake is shown at the end IIRC.
She never left it.
I don't want to spoil the ending but I would give you a really HUGE hint, you settle things with GLaDOS one and for all.

Few. After the ending of Portal 2, I doubt there would be a problem leading to Chell's Re-Entrance into Aperature. Since Glados was erased, it would make for a good storyline, but would re-hash Portal 1. Portal is still a good game, and it would always be dumb to put a money making game to rest. In the end, it's their choice.
