Atoms consist of a nucleus and electrons surrounding the nucleus. You can not change the nucleus by ordinary chemical means but you can remove electrons. However, since the electrons are easily replaced the atom is not considered fundamentally changed by removing electrons, but it is changed. There is a way to change a nucleus that's called "neutron activation" . This involves bombarding the nucleus with slow moving neutrons and letting the nucleus adsorb a neutron. This makes the atom a little heavier and can sometimes make the atom radioactive. Neutron activation is not considered a chemical process but it is a way to change the atom. So I would say it is incorrect to say an atom cannot be changed. Atoms can be changed but its not easy.

What ideas about atoms changed when new evidence was discovered?
atoms cannot be divided
When was the atom changed when new evidence was discovered?

What one of Dalton a four statements about atoms has been changed?
He said that atoms cannot be destroyed nor created, and atoms are indivisible but now the scientists can break atoms into parts so now they are no more indivisible. So the last law of Dalton's Atomic Theory have been modified.
How the radioactive decay rate be changed?
The rate cannot be changed.
Does an element become a compound when the type of atoms is changed?
Yes, the element changes to compound when atoms of it changes because compound is made up of different types of element and the element is made up of different types of atoms when the atoms are changed the element also changes and different types of elements are made due to this the element is changed to a compound.
What ideas about atoms changed when new evidence was discovered?

What changed about the atom when new evidence was discovered?

What cannot be changed into simple substances by chemical reaction or heat?
You think probable to atoms.
Substance that cannot be changed into simpler substances by chemical means?
An element is a substance that cannot be further broken down into simpler substances by chemical means. Each element is made up of atoms with a specific number of protons in their nucleus, giving them unique properties and characteristics. Examples of elements include oxygen, gold, and carbon.
How much do 4.81025 atoms weigh?
There is no such substance. There cannot be part of an atom (indicated by the decimal), there are only whole number of atoms. And even if you did say, how much does 4 (or whole number) atoms weigh, it could not be determined. This is because the particular element that defines the atoms has to be stated. Four atoms of oxygen will weigh differently than four atoms of lithium. Therefore, it cannot be answered.
Is there anything which cannot be changed?
Yes, there is. Death cannot be changed. Of course, who knows, maybe science can change that in the future! The past also cannot be changed.
Charges of atoms are changed by the movement of?
Charges are changed by the movement of electrons to or from an atom.
Can atoms mutate?
The Atom state can mutate but atoms themselves cannot
When was The Meeting Place Cannot Be Changed created?
The Meeting Place Cannot Be Changed was created in 1979.
What number cannot be changed in a chemical equation?
You cannot change the subscripts in the molecular identities.For example, H2SO4 must remain H2SO4 and not changed to something like H3SO7.Furthermore, the total mass of the reactants must equal the total mass of the products.
What is different about the atoms in a mixture than in a compound or element?
The atoms in a mixture it is whatever you want it Mixture's do NOT have a formula. All matter has atoms. For example a sandwich could have lettuce, tomatoes,cheese and meat or it can have two slices of cheese or even four pieces of meat. But as in a compound the atoms are not the same but it DO have a formula.For example water is a compound and have a formula of hydrogen 2 helium(H2O) that formula CANNOT be changed or broken becuase it is definte.Then in a element the atoms are the same and CANNOT be broken and has a definite formula.
