Not directly. Oxygen makes iron rust, and water helps.
Yes. The Sun has just about all the elements found on Earth, but in different quantities (lots of hydrogen and helium; much less of the heavier elements).
a star
when the supply of carbon is used up, other fusion reactions occur, until the core is filled with iron atom. +++ It is called a "star" - and it starts as hydrogen fusing to helium long before it forms carbon or iron. Iron is the end-product of medium-sized stars like our Sun.
tiny pieces of iron
Iron is naturally magnetized.
no iron is a metal
No. Iron melts at 1,538 degrees Celsius. The surface of the sun is at 5,500 degress Celsius, at which temperature iron is a gas.
The sun does contain some iron, around 0.2%. This would have been there at the birth of the sun, using remnant material from previous generations of stars.
it came from the sun.
A mole of iron (iron paper clips) Is nothing compared with the Sun.
Not in our Sun, but heavy elements up to and including iron are formed in very massive suns (stars). Elements heavier than iron are formed with suns die in a supernova.
No, the sun does not have an iron core to generate magnetic poles
in short, no!
Iron.
Iron is an element, and is the heaviest element that may be made by fusion in a Star such as our Sun.

A comet would not have enough iron to affect the Sun in any measurable way. Even a Jupiter-sized planet made of iron would not stop solar activity. The production of iron by a star is an endothermic fusion reaction. Any mass of iron nearing the Sun would be vaporized, and whatever entered the solar interior would circulate for many hundreds of years before any could reach the core.
There's hydrogen at the core of the sun - that's the sun's main fuel - but earth's core is mostly iron and nickel.
