A composition of an element is only fixed if it doesn't radioactively decay, chemically react, interact with a fundamental particle, and no external energy is introduced into the system. These four things happen quite a bit though and if they don't the element stays the same because it is at the lowest energy state it can obtain.

If the composition of a material is fixed?
If the composition of a material is fixed, it means that the material is made up of a set combination of elements in specific proportions. This fixed composition gives the material its unique properties and characteristics, which remain consistent as long as the composition is maintained.
Explain why the composition of an element is fixed.?
The composition of an element is fixed because each element is made up of a unique type of atom with a specific number of protons in its nucleus. This number of protons determines the element's identity, and any change in the number of protons would result in a different element. Therefore, the composition of an element cannot be altered without changing its identity.
What is a mineral that is only made up with one element?
A mineral is defined as a compound having a fixed chemical composition ... Thus an element is not a mineral.
Why is the composition of elements fixed?
A composition of an element is only fixed if it doesn't radioactively decay, chemically react, interact with a fundamental particle, and no external energy is introduced into the system. These four things happen quite a bit though and if they don't the element stays the same because it is at the lowest energy state it can obtain.
How do the atomic number change?
The atomic number of an element is FIXED it can not normally be changed. However, if the element's atom is struck by an atomic particle or the element is radioactive then the composition of the atoms nucleus can be altered. Changes to the composition of the nucleus can cause a NEW element to be formed or indeed split the atom into two NEW smaller/lighter atoms.
Is fixed composition a caracteritic of a mixture?
A fixed composition is not a characteristic of a mixture. The composition of a mixture can vary, unlike the composition of a compound that forms a chemical reaction.
What has a fixed composition and is always homogeneous?
A compound has a fixed composition and is always a homogeneous pure substance.
Does compound have a fixed composition?
Yes, compounds have a fixed composition because they are made up of a specific ratio of different elements bonded together in a precise manner. This fixed composition gives compounds specific properties and characteristics that are different from the individual elements that make them up.
Does the composition stays the same or pure substance?
A pure substance consists of only one type of element or compound. The composition of a pure substance always stays the same, with a fixed ratio of its constituent particles.
Which is a property of a pure substance uniform composition fixed composition varying composition?
A property of a pure substance is fixed composition. This means that the substance is made up of only one type of molecule or atom throughout, with no variation in its chemical composition.
Does mixtures have a composition?
Mixtures don't necessarily have fixed composition
Is nitre is an element mixture and a compound?
Nitre, also known as potassium nitrate, is a compound composed of potassium, nitrogen, and oxygen. It is not an element mixture, as it has a fixed chemical composition with a specific ratio of atoms.
