What chemical element is the primary constitutent of a young star?
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.
What is the lightest element in the universe?
Hydrogen. It is the lightest element in the known universe.
Is it true the group 1A elements except for hydrogen are known as the alkali metals?
Yes
Which region of the periodic table of the elements does hydrogen (H) belong to?
Hydrogen is the very first element of the periodic table.It is used in hydrogen fuel.It has atomic number 1.It is lightest element known.
What are the four elements needed by plants and animals in the manufacture of protein?
Those four elements are carbon, hydrogen, oxygen, and nitrogen (sometimes known collectively as CHON).
What produces all known element in the universe other hydrogen?

Is hydrogen the newest element?
Hardly. Hydrogen is one of the oldest elements known. It also comprises more than 98% of the matter in the entire known universe.
Does the first eighteen elements in the periodic table make up most of the matter of the 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.)

What are the two lightest gases in the universe?
In our known universe, hydrogen then helium. But this may change with further exploration.
What fraction of the mass in the known universe is made up of hydrogen and helium?
By mass, hydrogen = 75%, helium = 23%.
What process produces the largest amount of energy given off by stars?
Nuclear Fusion
What is the lightest element in the universe?
Hydrogen. It is the lightest element in the known universe.
What compound combines the elements oxygen and hydrogen?
A hydrogen bond combines oxygen and hydrogen in the H2O molecule also known as water.
Why are stars so important?
Stars play a variety of roles. First and foremost, the sun is a star. It provides the heat and light necessary for life of Earth. Stars also create most of the elements we find. Before stars started forming all matter in the universe consisted of hydrogen, helium, and trace amounts of lithium. All other elements have since been made in the thermonuclear furnaces of stars.
What other elements does polonium combine with?
Known compounds with oxygen, hydrogen, iodine, chlorine, bromine, etc.
What element has the lowest denisty of all of the elements?
Hydrogen is the least dense of all the elements and all other known substances.
