The statement is false.
When you change the number of neutrons in an atom, you create an isotope of that element, not a completely different element. The identity of an element is determined by the number of protons in its nucleus, which is also known as the atomic number. Neutrons contribute to the mass of the atom and can influence its stability and radioactive properties, but they do not change the element itself.
For example, carbon typically has 6 neutrons and is referred to as carbon-12. However, if you change the number of neutrons to 7, you have carbon-13, which is still carbon because it retains the same number of protons (6). Therefore, altering the number of neutrons results in different isotopes of the same element rather than a new element entirely.
