Stars combine Hydrogen to make Helium during nuclear fusion. Living things are made of heavier elements like Carbon Oxygen Iron and Calcium. How did these elements form?
answer?
Where did flourine come from?
Elements heavier than hydrogen were created over millions of years of nuclear fusion at the center of stars around the universe. As hydrogen nuclei are fused, they create helium atoms that can in turn also be fused under extreme amounts of pressure and temperature to make heavier elements, the cycle continues until elements such as iron are created at which point the star usually collapses. Elements more dense than this are created at the center of exploding stars under the pressure of one of the more powerful forces of the universe. Florine, being lighter than iron would be in the first category, having been fused from two other elements at the center of still active stars.
How are elements formed?
Hydrogen and helium were formed shortly after the creation of the universe (when the protons and alpha particles combined with electrons). Everything else was formed within the core of stars (by fusion reactions).
What two gases make up most of the atmosphere of the gas giants?
Helium and Hydrogen I'm in grade 9 and I know that =|
Characteristics of helium?
Helium is a gas which is very light. It is the second lightest element in the universe. Helium was discovered in 1986. William Ramsay confirmed it was helium. Helium remains as gas up to 25c (77f). Helium has no taste or no color. Helium doesn't combine with other elements. It is a by product of the reaction of hydrogen in the sun.
What are the two main elements of the sun?
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
What is the role of hydrogen and helium in the sythesis of elements?
Hydrogen and helium are the most abundant elements in the universe. And stars use them for power. To put it simply, hydrogen is fused into helium, and helium into carbon. All the heavier elements are made from there up through iron. The trans-iron elements are made is a supernova. It could be argued that hydrogen and helium are the basic building blocks of other elements.
Immediately after the Big Bang the universe contained?
Hydrogen, helium, small amounts of lithium. No heavier elements. Lots of the mysterious dark matter.Hydrogen, helium, small amounts of lithium. No heavier elements.

Element abundantly present in the universe especially in stars?
The two main elements in stars are Hydrogen and Helium. Stars start out as mostly Hydrogen and produce Helium. There are less amounts of heavier elements like Oxygen, Neon and Iron in stars
What are the 2 main elements in stars?
All stars are comprised of around 98% hydrogen and helium, of which approximately 3/4 is hydrogen.This is also true of all the matter in the universe as a whole.While stars contain some amount of pretty much every element, they are made primarily of hydrogen and helium.
What elements are presented in the stars?
The most common element in the Universe - and in most stars - is hydrogen. Stars have smaller amounts of helium, and still smaller amounts of "metals" (heavier elements). Some stars may have burnt out their hydrogen, and consist mainly of helium and heavier elements. It really depends on the star's stage in its life cycle.
Gas giants have atmospheres composed primarily of helium and what?

What is the fuel of a star in space?
Hydrogen , Helium and a few heavier elements.
What are the two most common elements of the universe?
Hydrogen and helium.
What element does a star run out of that causes them to die?
Hydrogen and helium; those two elements are the fuel for the stars. First they fuse hydrogen to helium, later they fuse helium to heavier elements.
Which is heavier hydrogen or helium?
Helium is heavier.
