Listen&Learn: How elements are madePosted by: Jaksyn Peacock
- element: one of the basic substances found on the periodic table
- abundant: existing in large amounts
- core: the centre of a planet or star
- fuse: to create something new by joining multiple things together
- collapse: to violently fall inward
- dense: containing a lot of material in a very small area
- remnant: a leftover piece of something that has been destroyed
See answers below
- The most abundant elements in the universe are
a. hydrogen and helium
b. hydrogen and carbon
c. helium and oxygen
- During its life, a star can’t use nuclear fusion to create
- Heavy elements can be made in a collision between two
c. neutron stars
- Scientists are beginning to experiment with nuclear fusion as a possible power source. Current nuclear power plants use a process called nuclear fission, which does not produce as much energy. What do you think about nuclear power? Do you think it will help or harm the environment? Why?
The simplest chemical elements in the universe, hydrogen and helium, originally formed during the Big Bang. These are the most abundant elements out there. The cores of stars can make more helium through a process called nuclear fusion, where enough energy forces the centres of atoms together to make more complex atoms. Other light elements, like oxygen and carbon, also originate from this process. Iron is the heaviest element that a star can fuse. This usually happens near the very end of the star’s life. There are two ways that heavier elements are made. The first is when stars, especially massive stars, collapse and die. The second is in a collision between two extremely dense star remnants, called neutron stars. These events create enough energy to fuse elements like lead and gold.

i am not afaird about anything about what happen because they are very carefully about safety. i think it is good for future generation and business side
Nuclear power generation is a challenge to mitigating climate change, so it’s important to be careful in preventing water and soil pollution.

Nuclear fusion can use abundant light elements to produce much more energy compare nuclear fission.
