Generally, yes. For stars on the main sequence, meaning that they fuse hydrogen at their cores, mass, size, color, brightness, and temperature are all closely related. More massive stars are larger, brighter and hotter than less massive ones. The least massive stars are red. As you go to more massive stars color changes to orange, then yellow, then white, and finally to blue for the most massive stars.
The stars in the constellation Scorpius exhibit a range of colors, including blue, white, and red. Blue stars are hotter and more massive, while red stars are cooler and less massive. The colors of the stars in Scorpius can vary based on their temperature and composition.

Red stars are cooler and less massive than blue stars. They emit light in the red and infrared parts of the spectrum, indicating lower surface temperatures. Blue stars, on the other hand, are hotter and more massive, emitting light in the blue and ultraviolet parts of the spectrum.
More massive stars burn their fuel at a faster rate due to the higher gravitational pressure in their cores. This causes them to have shorter lifespans despite having more fuel. The increased rate of fusion reactions in more massive stars exhausts their fuel reserves more quickly, leading to their quicker demise compared to less massive stars.
1st generation stars, also known as Population III stars, formed shortly after the Big Bang and consisted mainly of hydrogen and helium. They are believed to have been massive and short-lived. 2nd generation stars, or Population II stars, formed from the remnants of 1st generation stars and contain heavier elements produced in their cores. They are typically older and less massive than 1st generation stars.
Yes, both black holes and neutron stars are remnants of the death of massive stars. Neutron stars form when the core of a massive star collapses but does not produce a black hole. Black holes are formed when the core of a massive star collapses beyond the neutron star stage.
Iron is not formed in the Sun through nuclear fusion. Iron is the element with the highest nuclear binding energy per nucleon, making it less energetically favorable for fusion reactions to produce iron in the Sun. Iron is typically formed in the later stages of a massive star's life during a supernova explosion.
Younger stars often are made up mainly of hydrogen, perhaps with some helium. Less massive stars will only fues hydrogen into helium, so eventually they will end up having a lot of helium. More massive stars however will eventually start fusing helium to metals, i.e., heavier elements. In any case, the "metallicity" (percentage of elements heavier than helium) and the percentages of different elements should vary somewhat between different stars.Younger stars often are made up mainly of hydrogen, perhaps with some helium.

No, stars less massive than the Sun do not have enough mass to undergo a supernova explosion. Instead, they may end their lives as a white dwarf or, if they are even less massive, a planetary nebula. Supernovae are events associated with more massive stars.
Nuclear fusion.
Yes they can
Generally, yes. For stars on the main sequence, meaning that they fuse hydrogen at their cores, mass, size, color, brightness, and temperature are all closely related. More massive stars are larger, brighter and hotter than less massive ones. The least massive stars are red.

The most massive stars; they will use up their fuel much faster than less-massive stars. or even low mass star which is less then half the mass of our sun may able to last more then a trillion years that is longer then the universe age
The force that causes extremely high mass stars to turn into black holes instead of neutron stars is gravity. When massive stars exhaust their nuclear fuel and their cores collapse under their own gravity, they can either form neutron stars or black holes depending on their mass. If the core is more massive than about three times the mass of the sun, it collapses into a black hole due to the overwhelming gravitational force.
The more massive a star is, the less its life time.
The natural elements (like hydrogen, oxygen, carbon) formed during the Big Bang nucleosynthesis, where lighter elements were created. Heavier elements formed later in the cores of stars through nuclear fusion processes. These elements were then scattered throughout the universe when stars exploded in supernova events.
