What is the most common element in a star?

Question

A) Carbon
B) Helium
C) Hydrogen
D) Sodium

Answer 1

Hi. Hydrogen.

Answer 2

a star burns by converting hydrogen to helium, so hydrogen is the most common element but as the star burns out over billions of years the helium becomes more and more common and there is less and less hydrogen.

the answer is
C) Hydrogen.
.

Answer 3

This is a silly question as it depends on the age of a star as it turns Hydrogen into Helium but the answer they want will invariably be Helium (Our star was called Helios by the Greeks) but you could argue for either B or C depending on the star and it's age and size.

Answer 4

It really depends on the age of the star. Older stars tend to have more helium than hydrogen which causes them to nova and eventually collapse.

Answer 5

It's Hydrogen.

Answer 6

Depends on the star. Hydrogen in general, neutronium in a thin (~15 meters) iron shell for neutron stars, oxygen and carbon in white dwarfs, all helium in Wolf-Rayet stars...

Answer 7

C. Hydrogen.

Answer 8

my dear friend in a star hydrogen fuses into helium....................though the answer is hydrogen ut little more inf. will help..............................hydrogen atoms fuse to form helium and this reactions is called nuclear fusion reaction of hydrogen into heliumj and releases a massive amount of energy with a blast and is the reason for star's energy

Answer 9

C) Hydrogen! it is also the most abundant element in the entire universe!

Answer 10

Hydrogen.

Hydrogen atoms fuse together and form Helium plus large amounts of energy. ( Nuclear Fusion)
