Fusing hydrogen atoms into heavier elements produces helium and releases a large amount of energy in the form of heat and light. This process, known as nuclear fusion, occurs in the core of stars like our sun and is responsible for the sun's energy output.
In the current stage of the Universe, stars start off with lots of hydrogen-1 - and that's what they first fuse, since fusing heavier elements requires higher temperatures.Actually, hydrogen-2 (also known as deuterium) is even easier to fuse, but stars don't have significant amounts of that.
Hydrogen is the lightest element in the universe, with a single proton and one electron in its nucleus.
In 1818 there were 49 known and accepted (by the scientific community) elements.
The simplest substance known is the hydrogen atom. It is the most abundant element in the universe and consists of just one proton and one electron. All other elements in the periodic table are built by combining hydrogen atoms with other atoms through nuclear fusion processes.

Hardly. Hydrogen is one of the oldest elements known. It also comprises more than 98% of the matter in the entire known universe.
Yep. In fact, hydrogen alone makes up most of the matter in the known universe. Hydrogen is what the stars are made up of, and let's face it, stars are pretty big, and there's a bunch of them. Anything heavier than hydrogen (all the remaining elements) are products of nuclear fusion within stars, which has been going on since the beginning of the universe (15 billion years or so.)
is found in the form of hydrogen and helium. These elements were created during the Big Bang, and all other elements found in the universe were formed through processes like nuclear fusion in stars. Only a small fraction of the universe is made up of heavier elements like carbon, oxygen, and iron.

In our known universe, hydrogen then helium. But this may change with further exploration.
The lightest known element with only one proton is hydrogen. It is the most abundant element in the universe and serves as the building block for all other elements.

Nuclear Fusion
By mass, hydrogen = 75%, helium = 23%.
The first known element is hydrogen, which is the most abundant element in the universe. It is also the simplest element, with one proton and one electron in its atomic structure. Hydrogen is classified as a nonmetal on the periodic table.
