Why platinum is more expensive than aluminium and iron?
Iron & Aluminium are much more abundantly found as compared to platinum.Moreover in reactivity series aluminium & iron are found to much more reactive than platinum,platinum is least reactive.
A substance that has a high reactivity?
Phosphorus. Due to its high reactivity, this element can't be found in its free state.
What elements are found in platinum?
Platinum is an element.
Is platinum usually found in a compound or a pure?
Platinum is usually found pure.
Is an element's reactivity determined by the number of protons found in an atom of an element?
^.^
Platinum is never found combined with oxygen?
Platinum is one of the rare materials that does not oxidize at any temperature. It is also insoluble in hydrochloric or nitric acid. Breaking down platinum takes a caustic alkali, cyanide, halogen or sulfur.

Is the element platinum found free or is it chemically combined in nature?
Platinum usually exists uncombined in nature or alloyed with iridium.
Where can iron be found naturally?
Iron is found combined with Oxygen, in the form of Iron Oxide (also known as Rust).
Which non-metal is most often found combined with gold and other metals?
oxygen
Sulfur is often found in nature as an element not combined with other elements in a compound. What does this fact tell you about the reactivity of sulfur?
Sulfur is not a highly reactive element under ordinary condition.
Sulfur Is Often Found In Nature As An Element Not Combined With Other Elements In A Compound. What does this facts tell you about the reactivity of sulfur?
Sulfur is not a highly reactive element under ordinary condition.
What is the advantage of low reactivity metal?
Low reactivity metals can easily found in earth.
A substance that has a high reactivity?
Phosphorus. Due to its high reactivity, this element can't be found in its free state.
What are the two forms of copper ore?
Culprit and Chalococite. (Copper is found combined with oxygen to form culprit, or with sulfur to form chalcocite.
Why is platinum in a catalytic converter a element?
When a substance is an element, every single atom in that substance has the same number of protons. For instance, graphite is simply elemental carbon because every atom in graphite is a carbon atom. Water is not an element because each molecule of water contains two hydrogen atoms and one oxygen atom. Pure platinum is made up of many atoms with exactly 78 protons each bound together. Platinum atoms can be found in a few forms. To list a few, it can be combined with other metals in an alloy, it can be combined with certain atoms as a salt (platinum dioxide for instance), it can be found in a solution as an ion (Pt2+ for example), and it can be found as a pure sample of just plain old platinum. This is the case in your catalytic converter. When atoms bond chemically, their electrons interact. This changes their properties. In the catalytic converter, only platinum in the elemental form has the right chemical properties to change carbon monoxide into carbon dioxide, for example. This is why manufacturers use elemental platinum instead of something else. For an example of platinum that's not elemental, platinum dioxide is used as a different catalyst to make hydrogenated vegetable oils. It's not an element because it is bound to atoms with different numbers of protons (oxygen atoms). Hope this helps!
