What covalent structure is commonly known as sand?
Sand is silicon dioxide. Note that as sand is generally coloured the silicon dioxide contains traces of metal oxides, typically iron.
What are metal oxides with examples?
Metal oxides are oxides of metal. They are ionic in nature and form basic oxides. Eg: Na2O, MgO,etc
Is metal oxide is a base?
Yes, certain metal oxides, mostly from the middle groups of the transition metals are acidic. Chromium and rhenium, for example, both form oxides which are acidic in water.
What makes silicon like a non-metal?
Silicon is normally classified as a metalloid. It resembles a non-metal in the following respects:- elemental silicon is not a good conductor and is a brittle solid. In its chemistry silicon does not form ionic compounds where it is the cation. It has many resemblances to carbon forming silane SiH4, a gas, covalent compound- also there are compounds wuth chains of silicon atoms (although by no means as extensive as carbon) Its oxide is "acidic" whereas metal oxides are basic or amphoteric (react with bases and acids)
Are all oxides acidic?
No. A number of metal oxides are basic.
Is silicon natural?
Silicon is a marvelously abundant element, and it is most often found as an oxide. Many rocks are silicates, which are silicon oxides with a bit of metal thrown in. Sand us usually silicon oxides.
What is the pH number of silicon hydroxide?
It's below 7. All non-metal oxides and hydroxides are acidic.

Are metal's oxides gases or bases?
Metal oxides are typically basic.
Is silicon dioxide a sulfite?
No, Silicon dioxide does not dissolve in water. Better said, much less than glass does (glass is solid solution of silicon dioxide and alkaline metal oxides)
Is silicon magnetic?
Uh, no. It would have to be metal. It is normally non-magnetic BUT it CAN be magnetic if combined with one or more metals.
What is the difference between the chemical formula of sand and glass?
Sand is usually nearly pure silicon dioxide but may have other metal oxides also. The same is true for glass, but the fraction of material other than silicon dioxide is usually larger for glass. Neither of them is a pure compound; therefore neither of them has any exact chemical formula.
What are the names and chemical formulas of the two most common forms of carbon found in the atmosphere?
The most common state of oxygen is probably oxygen combined with metals and silicon such as molecules of silica which is sand and molecules of metal oxides like iron oxide. Aluminium oxides and Iron oxides and many other metal oxides make up most of the rocks and heavy material in the earth's crust. The sea contains a lot of oxygen as H2O which is water and the air is 20% oxygen, but the earth's crust weighs a lot more than the oceans and the air put together. Therefore it is very likely that the rocky oxides hold most of the Earth's oxygen.
Is silicon a metal nonmetal or semi metal?
Silicon is a semimetal.
