Is the composition of the interstellar medium about the same now as it was when the Sun was formed about 4 and a half billion years ago Why or why not How can you find out what it was like then?

The dust particles have exactly the same chemical composition as the gases of the interstellar medium?
false.
What is the most abundant element in the interstellar medium?
Hydrogen
The interstellar medium is enriched with heavy elements by the remnants of what?
The interstellar medium is enriched with heavy elements by the remnants of supernovas. A supernova is the spectacular explosion at the end of a stars life when it collapses in on itself.
Why do stars vary in chemical composition?
The change is mainly chronological ... in the beginning there was only hydrogen and helium, then as stars aged and exploded, heavier elements were introduced into the interstellar medium, and were thus incorporated into newer stars.
What is interstellar matter made of?
The interstellar medium is an extremely sparse (tenuous) mix of gas and dust, some of the gas being ionized, some atomic, and some molecular. By composition the gas is largely hydrogen, with smaller amounts of helium and very small amounts of heavier elements. There are also cosmic rays which are protons and nuclei which have been accelerated to near-relativistic speeds. In cooler, high-density areas, the interstellar medium can become as dense as one ten-billionth that of air.

Which of these is not a consequence of dust in the interstellar medium?
red light from the emission nebula
The dimming of starlight as it passes through the interstellar medium is called?
extinction
Does the interstellar medium have many chemical elements not found in stars?
No all Hydogen and most Helium is from the near beginning. All other elements including more He are formed by stellar processes
What makes up the interstellar medium?
The interstellar medium is all the matter that exists between the stars in a galaxy. It mainly consists of gas (99%), with about 75% of this gas being in the form of molecular or atomic hydrogen, and about 25% in the form of helium. The other 1% is in the form of dust. The density of the interstellar medium is also very small: about 1 atom per cubic centimetre.There are two main types of interstellar mediums:Cold clouds of neutral atomic or molecular hydrogen, which are the raw materials wherein stars can be formed if it becomes gravitationally unstable and collapses.Hot ionized hydrogen near hot young stars.
Which part of the interstellar matter produces reddening?
Visible light against electrons combined with ionized hydrogen create the "reddening" effect in the Interstellar Medium.
