Hydrogen, possibly helium but probably just hydrogen. All of the heavier elements in the universe today, including the vast majority of the matter that makes up Earth and its inhabitants (us!) were created in the nuclear fusion of stars.
A2. No one knows what (if anything) preceded or caused the Big Bang.
We infer that the laws of physics and time as we understand them, probably have no relevance at that time. The conditions even in the early phases of this event are beyond the realms of our physics.
Have a crack at Time line of big Bang in wikipedia.
A1. the big bang was made by a star exploding
Hydrogen, helium, and trace amounts of lithium were produced in the big bang. Mostly hydrogen, as you noted. The hydrogen coalesced into stars, which was fused into helium. In big, massive stars more of the elements were forged, primarily carbon, neon, silicon, and oxygen, on down to iron.
Elements heavier than iron are naturally produced only in supernova, and the subsequent radioactive decay of supernova elements. Note link below.
The components for the Big Bang Theory rely on Albert Einstein's General Theory of Relativity and the Cosmological Principle (homogeneity and isotropy within the universe). The core ideas of the Big Bang is that the Universe was filled homogeneously and isotropically with an incredibly high energy density and huge temperatures and pressures and was very rapidly expanding and cooling. The defining moment of the Big Bang is based on the entirety of our universe evolving from a one dimensional condition, known as a singularity; this is the moment before creation when space and time did not exist. According to the prevailing cosmological models that explain our universe, this ineffable evolution erupted to create not only fundamental subatomic particles, and thus matter and energy, but space and time itself. The equations of classical general relativity indicate a singularity at the origin of cosmic time and general relativity must break down before the Universe reaches the Planck temperature.
it was made of gas and powerful gusts of dust
The prevailing hypothesis of the Big Bang Theory is that the Big Bang formed from a singularity.
Yes, indirectly, but not as a separate element. Hydrogen is used in the Haber process to manufacture ammonia. This is then used directly as a fertilizer or used to create other ammonia based compounds e.g ammonium salts for use as fertilizer.
We can't create hydrogen and oxygen because they are natural, water is a mixture of both. Hydrogen and oxygen are elements and can't be made.
There are countless compounds composed of carbon, hydrogen, and oxygen.
Hydrogen and carbon do not create a new compound by themselves. To create a new compound, they would need to bond with atoms of more elements.
"electrifying water to separate the oygen and the hydrogen" (aka electrolysis) is very expensive and is only used to create laboratory grade hydrogen. According to this source: http://www.thenewatlantis.com/publications/the-hydrogen-hoax most commercial hydrogen is created from hydrocarbons, like natural gas and petroleum byproducts. The author of this article claims that creating hydrogen this way creates more CO2 than burning the hydrocarbons for fuel directly.
Nitrogen and Hydrogen.
Originally all elements come from one element, the most basic element that was before any other was Hydrogen, from hydrogen all other elements are created in a process called thermo nuclear fusion.Thermo nuclear fusion is the process in which elements heat up to such a temperature that they start to collide with each of the same element to create 1 element that is 1 step higher than the last 2. The periodic table can help you work out the order of what element was created by what. Just to give a quick few Hydrogen came first then 2 collided and created helium then the same process happened and created oxygen then carbon then sulphur and so on.There's another way of making the elements. Element hydrogen has 1 proton, 1 electrons and 0 neutrons. so its the lightest element in the periodic table. and helium, it has 2 protons, 1neutron and 2 electrons. So this is how scientist ACTUALLY created elements. The top mentioned way is to create water (H2O), and other moleculesThermo nuclear fusion is naturally taken place in stars (which have hydrogen on the outside, and as it goes deeper in, pressure changes it to helium), bigger stars can create more complex elements as they are hotter (more complex elements are heavier and will not collide at the same temperature hydrogen may do).A star of any size can only create elements as complex as iron, more complex elements than iron are created in the explosion of a large size.A question you may be wonering is how was hydrogen created. Nobody knows as far a society and scientists know.
Water was created through Chemistry. It is the combination of 2 Hydrogen molecules and 1 Oxygen molecule. When these 2 things come in contact they create water.
Helium is a naturally occurring chemical element therefore it can never have been invented but instead it was discovered. Though the above is true, Helium is the second lightest element in nature, right after Hydrogen, the lightest element. During the first 300,000 years after the Big Bang, ionized gases (plasma) combined together quarks and electrons to create Hydrogen, then eventually Helium, Carbon, Oxygen, and so on. So by "invent", I took it as you mean when was it first created in nature. It would have been first created when the first protons and electrons got together to mingle with neutrons, whom of which came later on, in huge molecular clouds that then created the first proton-stars.

Gold. Gold is an element, so it cannot be created from other elements.
The sun produces heat and light by the nuclear fusion of atoms of hydrogen to create helium. The hydrogen it uses was created during the cooling of the universe after the Big Bang. hydrogen is the major "fuel" of the sun.
During the depression, it created jobs.
No, nuclear power plants get their energy from fissionof the heavy element uranium, the sun gets its energy from fusion of the light element hydrogen.
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
Elements are Elemental, you "cannot" create them, they were already here. Man has created many alloy's & composites, but man has never created an "element". This all occurred micro-seconds after the big bang.
particles come together by the gravitational force. hydrogen occures and while this is happening the energy is created
