How many electrons represent a complete (filled) outer most energy level for elements heavier than boron (atomic number greater than 5)?
Eight electrons represent a complete (filled) outermost energy level for elements heavier than boron. This is because the outermost energy level can hold a maximum of 8 electrons according to the octet rule.
The heavier elements in the universe were formed by .?
They were formed in supernovae.
How are heavier elements formed from hydrogen within the core of a star?
Heavier elements are formed through nuclear fusion processes that take place in the core of a star. Hydrogen atoms undergo fusion to form helium, and then this process continues to create heavier elements by fusing helium atoms together. As the star fuses lighter elements, it produces heavier elements through a series of nuclear reactions.
How are elements heavier than hydrogen formed?
Elements heavier than hydrogen are formed through nuclear fusion processes in stars. When lighter elements fuse together in the intense heat and pressure within a star's core, they can form heavier elements. This process continues throughout a star's life until elements up to iron are created. Elements heavier than iron are formed through supernova explosions or in the collisions of neutron stars.
What is the term describing the fusing of lighter elements into heavier elements?
That process is known as nuclear fusion. In nuclear fusion, lighter elements such as hydrogen combine to form heavier elements, releasing energy in the process. This is the process that powers stars like our sun.

Why is the earth's outermost layer composed mostly of lighter elements?
The Earth's outermost layer, the crust, is composed mostly of lighter elements like oxygen and silicon because these elements are more buoyant and rise to the surface during the Earth's formation due to differentiation. Heavier elements tend to sink towards the Earth's core, leaving lighter elements to form the crust.
How are elements heavier than iron are formed?
Elements heavier than iron are formed in super-nova explosions.
The heavier elements in the universe were formed by .?
They were formed in supernovae.
What is the composition of lighter elements in comparison with heavier element?
Lighter elements are composed of fewer protons and neutrons compared to heavier elements. They tend to have fewer total nucleons and lower atomic numbers. Lighter elements are typically found at the beginning of the periodic table, while heavier elements are found towards the end.
What it a process in which lighter elements stick together to create heavier elements?
This process is known as nuclear fusion. It occurs in stars like the sun when lighter elements such as hydrogen are combined to form heavier elements like helium, releasing a large amount of energy in the process.
What is heavier than air?
Almost all solid elements are heavier than air. This is why these elements do not float under normal atmospheric situations.
What fuel is used by red giant stars?
After using up its hydrogen-1, the star becomes a red giant. It will start fusing helium-4 into heavier elements. It may also fuse heavier elements, to get other elements that are yet heavier.
Why does your sun have 2 percent heavier elements and from where do they come?
I think it's our Sun which gets heavier elements from fusion of hydrogen and other light elements.Edit: Our Sun does create helium from hydrogen by fusion, but that's all. The reason it has heavier elements is that these come from the nebula that formed the Sun. The heavier elements are thought to have come from stars that exploded as "supernovas", a long time ago.
What happens with fusion of heavier element?
When heavier elements undergo fusion, they release energy in the form of light and heat. This process can only occur in extreme conditions, such as the high temperatures and pressures found in stars or during a thermonuclear reaction. Fusion of heavier elements can lead to the formation of even heavier elements and can release a tremendous amount of energy.
What is produced within a star's core?
New elements - helium always, heavier elements often (up to iron) and heavier than that if the star explodes.
