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).
When elements join together, they form compounds. Compounds are made up of two or more different elements that are chemically bonded together. This bonding can be either covalent (sharing electrons) or ionic (transferring electrons).
Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.
Carbon dioxide (CO2) is formed from its elements (carbon and oxygen) by an exothermic reaction at 298 K and 101.3 kPa.
Most of the atoms in living things come from just six elements. These elements are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. Scientists theorize that these elements, along with all 93 natural elements, were created in the centers of stars billions of years ago, shortly after the universe formed in a violent explosion.
A few elements past iron can form in the star by neutron capture and beta decay. However the majority can only be formed by the blast shockwave of a supernova, which can form elements significantly beyond Uranium.
Compounds are formed from elements.
It is said that when sun dies from hydrogen to iron elements are formed and when busted spread in space .the other elements are formed by chemical reaction by these elements
Compounds are formed when elements of matter are chemically combined.
Elements are formed from atoms. Atoms are formed of protons, neutrons, and electrons (sub-atomic particles).
The heart does not make the formed elements of the blood. The formed elements are made in the bone marrow. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Compounds are formed when elements of matter are chemically combined.
Compounds are formed when elements of matter are chemically combined.
Eosinophils are the formed elements that counter parasitic worms.
They were formed in supernovae.
That depends on the elements.
They were formed in supernovae.
Water is a COMPOUND because it is formed from atoms of two elements.
