100

This stage in the stars life would show that the star is nearing the end.

What is a Dwarf Star?

100

The reaction of two or more nuclei being combined.

What is nuclear fusion?

100

This is what the H-R diagram compares.

What is temperature/color against luminosity?

100

The vertical columns of the periodic table.

What are groups?

100

This part of the atom orbits the nuclei.

What is the electron?

200

This stage of the star life cycle represents the first signs of a physical star.

What is a protostar?

200

This is what Helium fuses into.

What is carbon?

200

Cooler temperature stars will most likely have this color.

What is red? (orange will also be accepted)

200

The horizontal rows of the periodic table.

What are periods?

200

This part determines the atomic number of the element.

What is the proton?

300

You'd expect this kind of fusion in a main sequence star.

What is hydrogen fusion.

300

This is where nuclear fusion occurs.

What is the star's core?
300

When looking at main sequence stars, the more luminous stars would be this temperature. (not specific temperatures)

What is higher temp?

300

The element in period 5, group 17.

What is Iodine?

300

Small units of matter that make up elements.

What are atoms?

400

You'd expect to see Oxygen fusion in this star stage.

What is a red super giant star?

400

This is what oxygen and helium would fuse into.

What is Neon?

400

This is what H-R diagrams are typically used for.

What are study of stars/evolution/collections?

400

Collections of elements with similar properties.

What are families?

400

This element has an atomic mass of 32, and 16 neutrons.

What is sulfur?

500

This is what occurs between most transitions between star stages.

What is fusion stops, gravity shrinks core, pressure and temp rise, fusion begins with heavier elements?
500

This is what is needed for fusion to occur.

What is high temp & high pressure?

500

The least luminous star collections based on the H-R diagram would be these stars.

What are white dwarfs?

500

The number of valence electrons in Arsenic.

What is five?

500

Titanium has 22 protons and this many neutrons.

What is 26 neutrons?
