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.
No, compounds containing metals are not always soluble in water. The solubility of a metal compound in water depends on various factors such as the specific metal, the anion present in the compound, and the conditions such as temperature and pressure. Some metal compounds are soluble in water, while others are insoluble.
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.
These are called nonmetals (e.g. carbon, phosphorus, sulfur)Metals (such as gold, titanium, and cobalt) are generally lustrous, malleable, and can conduct electricity. Nonmetals are dull, extremely brittle, and are usually (but not always) non-conductive.
Yes, water vapor is a naturally occurring component of the Earth's atmosphere. Its presence can vary depending on factors such as temperature and location.
A continuous resource is a natural resource that can be replenished or regenerated at a rate equal to or greater than its rate of consumption or use by humans. Examples include solar energy, wind energy, and water resources from sources like rivers and lakes.
In a galvanic cell, the metal that acts as the anode is the one that has a higher tendency to oxidize, meaning it loses electrons more readily. Typically, in a setup involving metals, zinc is often used as the anode because it has a more negative electrode potential compared to many other metals like copper or silver. However, the specific metal that will always be an anode can vary depending on the electrochemical context and the metals involved.
No, a metalloid is not always a synthetic metal. Metalloids are elements that have properties of both metals and nonmetals, and they can be found naturally in the earth's crust. Examples of metalloids include silicon, arsenic, and germanium.
When acids react with active metals, they always produce a salt and hydrogen gas.
No, metals always expand when heated and contract only when cooled.
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.
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.
It comes naturally.
Alkali metals are not found as pure elements in nature.
C-11 is virtually always for Corporations.
Yes, anyplace. virtually always is.
5.6 of anything is virtually always equivalent to 5.6 of them.
Electrical conduction in metals nearly always (you can have conducting polymers keep in mind)
