False.
Atoms themselves only change during nuclear decay, fusion or fission. Outer electrons can be shared, donated or received during bonding but the atom doesn't change in and of itself.
When matter changes state the bonds themselves are not affected. All that happens in a change of state is that molecules gain more kinetic energy. The bonds within the molecules are not altered.

Nuclear reactions such as fusion and fission convert?
Nuclear reactions convert very small amounts of matter into significant amounts of energy.
Are ecosystems transformers of matter and energy?
In an ecosystem the reactions going on are chemical reactions, and the total weight of the substances involved remains constant. Matter is only destroyed in nuclear reactions such as the fission of uranium, which does not happen in a normal ecosystem. Energy is transformed though, for example the sun's energy is absorbed by plants making them grow.
What is chemical?
Any physical matter can be considered a chemical. Chemical reactions are of two types. The more common reactions revolve around the interactions of electron clouds and the transfer of electrons among them. While the rarer form, nuclear chemistry, involves either the input of energy to create matter or the degradation of matter to release energy.
A sphere of matter held together by its own gravitational field and generating nuclear fusion reactions in its interior?
A star.
What are the conservation laws of nuclear reactions?
Please anyone tell me answer I need it thanks
Nuclear reactions such as fusion and fission convert?
Nuclear reactions convert very small amounts of matter into significant amounts of energy.
Nuclear reactions produce huge amounts of energy by transfroming tiny amounts of matter?
into energy.
Do nuclear reactions produce huge amounts of energy by transforming tiny amounts of matter?
Yes, it is actually annihilation of matter that produces the energy in nuclear fission, which is the reaction that powers power plants
How this energy formed?
Energy hasn't been formed since the creation of matter. However, energy is present in atoms and can be released during chemical or nuclear reactions.

What is Einstein exception of the law of conservation of energy?
The law of conservation of energy itself is not strictly correct since nuclear reactions change a small amount of matter into energy, if this is what you mean.
When metamorphic rock melts and turns into lava is matter conserved?
Yes, this is a simple physical change and matter is always conserved in these. In fact, matter is always conserved except in nuclear reactions where the sum of matter and energy is conserved.
What type of reaction releases the most eneergy?
I guess that would be when a "regular" particle meets an antiparticle - in that case, 100% of the mass of both particles will be released as energy.Next come nuclear reactions, where usually something like a fraction of one percent of the matter gets released as energy. Chemical reactions release about a million times less energy than nuclear reactions.
What is the explanation for the principle of conservation of matter?
Matter cannot be created or destroyed. It can only be changed from one form to another. However, Einstein and other scientists have shown us that matter and energy are interchangeable. Matter is changed into energy in the sun and in other nuclear reactions, (E = mc2).
What formula developed by Albert Einstein describes the relationship between energy and matter?
What formula, developed by Albert Einstein, describes the relationship between energy and matter? "Nuclear reactions convert matter into energy. In 1905, Albert Einstein developed a formula that described the relationship between energy and matter. You have probably seen this famous equation, E=mc2. In the equation, the E represents energy and m represents mass. The c, which represents the speed of light, is a very large number. This equation states that when matter is changed into energy, an enormous amount of energy is released."
Why does not law of conservation of energy apply to the nuclear reactions?
A percentage of the matter is liberated as energy. Fusion reactions tend to convert more mass to energy than do fission reactions. Proton and neutron counts are preserved, but the mass of a helium nucleus is less than the rest mass of the particles of which it is comprised--two neutrons and two protons. The difference is known as the "mass defect," and is equivalent to the energy released in a fusion reaction. Similarly, fission reactions (the splitting apart of atomic nuclei) also liberates energy in a variety of forms. Note: Mass/Energy is conserved in ANY reaction. But as mass may be converted into energy, and vice versa, the mass itself is not necessarily conserved.
When matter creates a new matter?
Nuclear physicists have theorized that it is possible to transform matter into energy and energy into matter.
