How would a silicon based metabolism even work?

The idea is that silicon could replace carbon because it has the same valence.

The problem is that Silicon is much larger and does not allow for as much variance and complexity as Carbon.

It would continously shit bricks of silicon dioxide

There is this one shit old movie called "evolution" where alien life forms evolve on earth and fuck shit up.
They find the poison, somehow since arsenic is toxic to carbon-based life selenium is toxic to silicon based life.
Then they defeat the abeans with head and shoulders shampoo

>>8910853
Wouldn't antimony have made more sense?

>Ira theorizes selenium might be poisonous to the aliens, since they are nitrogen-based, as arsenic is poisonous to Earth's carbon life.

They're nitrogen based.

My grade 10 biology teacher mentioned this to me but I never bothered to look up the movie.

The premise was that since Arsenic is down two rows and one column to the right on the periodic table in relation to Carbon, the same L-shaped jump would make Selenium poisonous to Nitrogen-based life forms.

That movie was actually what made me decide chemistry is retarded and started my career path toward physics.

How the fuck would Nitrogen based life even work? What next, Chlorine based life?

I used to love chemistry back in HS. I used to think I'd either go into Chem E or a related field. I've since changed my mind, but I recently took an intro chem course as a prereq for my entrance to major (returning to education using the GI Bill) and was astonished at how much the course made me hate it.

>was astonished at how much the course made me hate it

What exactly made you hate it? I haven't taken a chemistry class since early high school

>>8910933
The banality of the material and the methods of the course.
>Have to pay an extra fee to take an online assessment (ALEKS) which takes hours to complete and aside from it affecting 2% of your final grade has no real utility
>all """critical thinking""" questions are tired algebra tricks
To be fair that last one is a fucking common one among courses I've taken. It almost feels like some administrators told the course directors to add "critical thinking" questions, and in their laziness they resort to these algebraic manipulations.

Movie was a 2 hours head and shoulders comercial
You can't find any antimony in head and shoulders now can you

>>8911030
this is the first thing I think of when I think silicon based life
