by the process of nuclear fusion
Elements heavier than hydrogen are formed through nuclear fusion processes in stars. When lighter elements fuse together in the intense heat and pressure within a star's core, they can form heavier elements. This process continues throughout a star's life until elements up to iron are created. Elements heavier than iron are formed through supernova explosions or in the collisions of neutron stars.
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

Heavier elements in the universe are primarily formed through nuclear fusion processes within the cores of stars. Elements beyond iron are typically formed in supernova explosions, where the extreme conditions allow for the synthesis of elements such as gold, silver, and uranium.
A covalent bond is formed between the hydrogen and oxygen atoms within one water molecule. In this bond, the atoms share electrons to achieve a stable configuration.
HCl is a compound, liquid at normal temps and pressures; called hydrochloric acid. The elements in the compound are hydrogen and chlorine.

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).
Heavier elements are formed through nuclear fusion reactions in the core of a star. Hydrogen atoms are fused together under high pressure and temperature to form helium. Further fusion reactions involving helium nuclei lead to the formation of heavier elements like carbon, oxygen, and up to iron. These elements are produced through a series of nuclear reactions that occur as the star evolves.

Everything except Hydrogen & Helium (and part of the Helium is also formed within stars).
The matter of the Universe was scattered in space; stars and galaxies formed much later. By the way, only hydrogen (#1) and helium (#2) existed in the beginning, and perhaps a small amount of lithium (#3); the "metals" (i.e., heavier elements) were formed later within the stars, through fusion.
A star is made up of Hydrogen and Helium, (the Helium coming from the fusion of Hydrogen atoms). When a star goes super nova, it is so hot that it fuses together gases so rapidly that it creates all of the elements on the periodic table.
No.All elements (since the creation of the Universe) are formed by either combining two lighter elements in to a heavier one (called nuclear fusion) or by splitting a heavy element into 2 (or more) lighter ones (called nuclear fission).It is believed that at the creation of the Universe mostly hydrogen (and some helium) was present. Hydrogen is by far the most common element. These are the two lightest elements. Inside stars these elements are fused together to form heavier elements. Our very own Sun, for example, fuses hydrogen atoms together to form helium. This process releases energy in the form of heat and light.A star is able to do this due to the tremendous heat and pressure within it. There are different types of stars, and some have even more staggeringly high pressures inside them allowing them to fuse together and form heavier elements than helium. It is believed that when a star dies, and goes supernova, the tremendous force at this point can fuse and create even heavier elements still. This explains why the heaviest elements are the rarest elements.So, we have stars to thank for all the elements that exist. The pressures and temperatures within the Earth are just not high enough to fuse atoms together.
Nuclear Fusion Processes, those that form new elements, require both high temperatures and pressures. These are only found at or near the center of the star. Hydrogen fusion is the easiest (excepting deuterium but that's a bit too detailed for here) and takes place in the smallest of stars. (Brown Dwarves don't count as no fusion is going on there). For successively heavier fusion reactions creating heavier elements higher temperatures and pressures are required and therefore take place nearer the center of the star within the sphere of hydrogen fusion. The very largest star therefore have an onion like structure where more and more internal layer are forming heavier and heavier elements. The heaviest element that can be formed by energy producing reactions is Iron. After that the formation of even heavier elements absorbs energy. This is why all the elements above Iron are thought to form in Super-novas reactions where there is incredible temperatures and pressures and no worry that energy absorbing reactions are going to shut things down.
New elements - helium always, heavier elements often (up to iron) and heavier than that if the star explodes.
At the time of the big bang there were no elements. Within a third of a million years (after it had cooled a bit) it ended up with mostly Hydrogen and Helium (with traces of Lithium). Everything else had to wait for stars to be born, use up their fuel (hydrogen) and die.
