Other elements were formed in stars by nucleosynthesis.
answer?
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.
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).
Helium and Hydrogen I'm in grade 9 and I know that =|
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.
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.
Hydrogen and helium are the two most abundant elements in the universe.
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.

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
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.
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.

Hydrogen , Helium and a few heavier elements.
Hydrogen and helium.
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.
Helium is heavier.
