in its pure form, iron is an element, but that may not be what you are referring to.... if you have iron oxide (rust), this is a compound of iron and oxygen.
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
Nitrogen is an element . Nitrogen gas, however, is often called nitrogen and is a molecule consisting of two nitrogen atoms bound together. Thus it may be considered to be a compound.
No, diamond is a form of the pure element carbon.
False. A molecule is the smallest part of a compound that can still be indentified as a compound as it may contain several atoms of different elements. A single atom can only identify a single element, not a compound which it may have been a part of.
in its pure form, iron is an element, but that may not be what you are referring to.... if you have iron oxide (rust), this is a compound of iron and oxygen.
Iron is a chemical element; sand may be a compound or a mixture.
elements that may form a compound, are elements that are different from each other, and they also have to be more than 1 element to combine, and create.
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
No. If it is written Ar, it is the element Argon. If not, it may be the acronym for a longer-named compound, but it cannot be a chemical formula.
substance
Iron is an element, and is the heaviest element that may be made by fusion in a Star such as our Sun.
substance
Because they are, respectively, an element and a compound. There may be a deeper question here, but I'm not seeing it. Perhaps you're trying to ask what the difference is between an element and a compound?
To form a compound.
A solid may be an element (iron), a compound (iron oxide), a mixture (iron ore).
A molecule is the smallest particle of an element. An element is one of a table of unique elements each in their purest form. A compound is the chemical bonding of two or more elements. So, as you can see, a molecule is not at all similar to a compound.
