Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.

What is a chemical reaction and how are reactants and products involved?
A chemical reaction is a change in which one kind of matter changes into a different kind of matter with different properties. Reactant is a substance used in a chemical reaction and a product is a substance made in a chemical reaction. Hope this is helpful! ;)
Can rocks change from one one kind to another kind any order?
Yes, rocks can change from one kind to another through processes like metamorphism (changing due to heat and pressure) or weathering (breaking down into smaller particles). The rock cycle illustrates how rocks can continuously change from one type to another in any order.
When do the atoms of one element break down to form atoms of another element?
Atoms of one element break down to form atoms of another element through the process of nuclear fusion, which occurs in the core of stars during stellar nucleosynthesis. This process involves the combination of atomic nuclei to form heavier elements, releasing energy in the form of light and heat.
What is a series of processes that slowly change rocks from one kind to another?
The series of processes that slowly change rocks from one kind to another is called the rock cycle. This cycle involves processes such as weathering, erosion, deposition, compaction, and cementation that transform rocks from one type to another over long periods of time.
What do you have to do to release the energy of a fuel?
To release the energy of a fuel, you need to burn it in the presence of oxygen. This combustion process causes a chemical reaction that converts the potential energy stored in the fuel into heat and other forms of energy.
What kind of reaction can change an element into another?
Fusion or fission.
What kind of decay can change one element to another kind of element?
That would be radioactive decay.
What reaction has occurred when one element replaces another in a compound?
This kind of reaction is usually called a "single displacement" or :single replacement" reaction.
Can gold be changed into another element?
An element can only change if the number of protons in its nucleus changes. It is possible to make one kind of element into another, but all these processes can be accomplished only by nuclear means. Gold can be changed into another element in a physics lab, but only with the use of a nuclear reactor or an accelerator of some kind. Any element can be changed into another element, but only by nuclear means.
What kind of reaction is represented metal plus water equals metal hydroxide plus hydrogen?
This reaction is a single displacement reaction, also known as a displacement reaction or a replacement reaction. In this type of reaction, one element replaces another in a compound.
If a compound x reacts with another compound y to form a compound z what kind of change would this reaction represnt?
The reaction would be a combination reaction. This type of reaction is also sometimes referred to at a synthesis reaction.
What kind of reaction occurs when one element replaces another in a compound?
This is called a replacement reaction. When one element replaces another in a compound, it is called single replacement or single displacement. An example isZn + 2HCl ---> ZnCl2 + H2 where the zinc replaces the hydrogen in the acid to form zinc chloride.
Fission and fusion is an example of what kind of energy?
One type of atom (element or isotope) is converted to another. This is called nuclear reaction.
What kind of change must occur for an element to be removed from its compound?
a chemical change
Every what has its own kind of atom?
Every element has its own kind of atom, identifiable from atoms of another element by its number of protons.
What kind of change happens when hydrogen gas and oxygen gas react burn and form water?
This reaction is a chemical change.
What can the atomic number and what things can it identify?
The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.
