No, a white dwarf is a small, dense star that has exhausted its supply of nuclear fuel and is no longer able to sustain nuclear fusion reactions in its core. White dwarfs are the remnants of stars that were once similar to the Sun, and they are typically about the size of Earth but much more massive. They are called "white" dwarfs because they are extremely hot and glow with a white-hot light, but they are not capable of fusing elements because they do not have the necessary conditions (temperature, density, and pressure) to sustain nuclear fusion in their cores.

∙ 13y agoFirst of all a white dwarf is a small (Earth sized) stellar remain of a star that was around the same size as our own Sun.
It's remains are the "left over" bit, when a star reached a point when it could no longer fuse anymore elements. It did not have enough mass to continue fusing any further elements. Larger stars can, but they do not leave behind a white dwarf.
However, if a white dwarf is near a companion star and can accrete enough mass to exceed the Chandrasekhar limit [See related question], then the star can start fusing additional elements, and the star will explode as a type la supernova. [See related question]

Which is capable of independent existence an atom or molecule?
Atoms of most elements are not able to exist independently. Atoms form molecules or ions aggregate in large numbers to form the matter that we can see. Molecule is capable of independent existence.
How large is a black dwarf?
The same size as the white dwarf it was. See related question.
The clouds of Magellan the Sagittarius dwarf are examples of what galaxies?
The Large Magellanic cloud is an irregular galaxy.The Small Magellanic cloud is a dwarf galaxyThe Sagittarius Dwarf is an elliptical galaxy
Are dwarf planets asteroids?
No. The term dwarf planet is reserved for a relatively large object that is rounded by its own gravity. The vast majority of asteroids are not rounded like this.
Where are most dwarf planets from?
Most of the dwarf planets are large Kuiper belt objects, bodies that are in a distant orbit around our sun, beyond Neptune's orbit.
Is it true or that a white dwarf is a large star capble of fusing elements?
no
What are some characteristics of stars that might account for the fact that some have more complex elements in their spectra?
Older age might account for it. As a star ages, it uses up the simplest elements (hydrogen . . . helium . . .) then starts fusing heavier and heavier elements. Our Sun will get to the point of fusing iron, which is pretty heavy, but the truly large stars out there will fuse elements much heavier than Iron. These heavier and heavier elements may account for some stars having more complex elements in their spectra.

Why are fungi capable of reproducing in such large numbers?
They are capable of reproducing in large numbers because they have spores
What is a very large dwarf planet?
Eris is thought to be the largest of the five dwarf planets.
How large is a black dwarf?
The same size as the white dwarf it was. See related question.
What is the matter contained in a white dwarf?
A white dwarf consists of the core of the large star it once was.
What characteristics do red stars share?
They are either small and cool and fusing hydrogen or large and hot, fusing helium. The large and hot ones ape read because although they are hot, this heat is radiated over a large surface area. Large red stars are approaching the end of their lives, small, cool red stars will have very, very long lives.
What are two categories of the size of galaxies?
Large and Dwarf.
How large is a white dwarf?
Around 12,742 km.
What heats the sun?
Fusing of hydrogen into helium gives large amounts of heat the process is called nuclear fusion
Do African dwarf frogs need a large tank?
No they don't.
