Do the mineral groups carbonates, halides, or sulfides contain silicon?

Answer 1

No they don't

Only those minerals are put in silicate group which have #Si# (silicon) and oxygen combined in their chemical formula. For example

#SiO_2 -># Quartz

#Fe_2SiO_3#

#Mg_2SiO_3 -># (Olivine)

Carbonate have carbon and oxygen. For example #CaCO_3# (calcium carbonate)

Halides have combination of salt forming elements of 7th group (#F#, #Cl#, #Br#, #I#) with other elements. For example #CaF_2# , #NaCl# etc

Sulfides have #S# (sulfur) with other elements like #ZnS#, #PbS#

Conclusion: Silicon is only found in silicates.

I hope this is useful. Thank you.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
