What else can I help you with?
What is a characteristic of nonmetal a?
One characteristic of non-metals is that they are generally gaseous at room temperature. Non-metals will also typically bond with metals easily.
Is carbon and silicon gaseous non metals?
Yes.
Are all non-metals brittle?
No, all nonmetals are not brittle. Oxygen,Hydrogen,Nitrogen etc. are some of the nonmetals that occurs in gaseous form.
What charges do metals and non-metals usually form?
Metals are usually positive and non-metals are usually negative.
Do non metals react with water?
Most of them do NOT react with water. Only fluorine and to some extend chlorine do. Actually the only good 'water reacting' group of elements is group 1: the alkali metals.
What pair of atoms will form ionic bond?
A metal tends to form an ionic bond with a non-metal. Metals bonding with other metals form a metallic bond, and non-metals bonding with other non-metals form a covalent bond.
What type of bond do non metals form with other non metals?
Covalent :)
Are Non-metals are very likely to form ionic bonds with other non-metals?
No, non-metals are more likely to form covalent bonds with other non-metals because they tend to share electrons rather than transfer them. Ionic bonds typically form between metals and non-metals due to the large difference in electronegativity.
Is it possible for non metals and metals to form non polar covalent?
Yes, it is possible.
Which type of elements gain electrons when they form bonds?
It is done by Non-metals and metalloids.They form anions
When elements combine they form what compounds?
If the elements are both non-metals, they form a molecular compound. If they are both metals, they form a metallic bonds. If they are a metal and a non-metal they form ionic bonds (salts). (Ammonium salts are non-metals.)
What is the oxidation number of non metals?
The oxidation number of non-metals can vary depending on the element and the compound it is in. Generally, non-metals tend to have negative oxidation numbers when they form compounds with metals, but they can also have positive oxidation numbers when they form compounds with other non-metals.
