Metals may naturally oxidize and virtually always have the same oxidation number. An oxidation number is assigned to an element in chemical combination that represents the number of electrons lost or gained.

Is compounds containing metals always soluble in water?
By soluble I presume you mean soluble in water and, in that case, the answer is, some are and some are not. For example, Ferric Oxide Fe2O3, usually known as rust, is not soluble in water, whereas Sodium Chloride NaCl, usually known as table salt, is soluble in water.
Are there any metals that attract each other like magnets?
Magnetism is a condition of being, not a type of metal, and metals don't typically attract metals. Anything containing iron can become magnetized. All it takes is exposing it to a magnet or applying a DC current to a coil wrapped around it.
Why does boron not always continue the Period 2 pattern of reacting by losing electrons?
because its a metalloid and the rest are all metals
Is metallic elements more likely to lose electron than nonmetallic elements?
Yes. Metals always lose electrons and non-metals gain electrons.
What is a continuous resource?
If you mean a renewable resources then water power, wind power, and solar power are all considered to be renewable.
Do any metals contract when heated?
No, metals always expand when heated and contract only when cooled.
Which rusts faster iron or steel?
Iron rusts faster in theory, but it all depends on the conditions. Steel is just Iron mixed into an alloy with Carbon and (sometimes) a few other metals. There are many different grades and types of both Iron and Steel, and they all oxidize at slightly different rates. In short, oiled or finished steel will give you a fair amount of rust resistance, but it is always necessary to maintain metals to prevent oxidation.
Are alkali metals always found pure in nature?
Alkali metals are not found as pure elements in nature.
What was the cutlery made of in Medieval Times?
Spoons would be made of wood or bone (for the peasants) and iron or other metals for the nobility. Knives were made of metal, as always, although people simply used their beltknife rather than a specialised implement. Forks were virtually nonexistent.
