No: for example, none of the other elements contains any amount of these two elements. Other large classes of substances free from oxygen and silicon are halides and hydrocarbons.
Yes; that is implied by the name "silicate".
Silicone materials are partly made of the element silicon, but most or all the silicon atoms in them are also bonded to oxygen atoms. Therefore, silicone materials do not have the chemical properties of pure elemental silicon.
Silicon is an element so it doesn't contain anymore than one. You may have meant silicone though, which is a group of compounds and usually contain silicon, oxygen, carbon, and hydrogen. I think the answer you're specifically looking for would be Si and O.
They are classified based on the structure of their silicate group. Silicate minerals all contain silicon and oxygen.
No, they are not.
Silicates contain mostly silicon and oxygen. The different types of silicate also contain other materials, but the base materials are silicate and oxygen
Yes; that is implied by the name "silicate".
silicon and oxygen
silicon and oxygen
No. Silicates do however.
Silicon and oxygen.
They all contain the silicon-oxygen tetrahedron.
silicon and oxygen apex :p
sulfur and four oxygen atoms
Silicone materials are partly made of the element silicon, but most or all the silicon atoms in them are also bonded to oxygen atoms. Therefore, silicone materials do not have the chemical properties of pure elemental silicon.
The two elements that must be present in a silicate are silicon and oxygen.
All materials and that includes minerals contain the elements. Sulfates contain sulfur and oxygen
