/the atomic structure defines the substance....changing the atomic configuration changes the substance to something else.....
it would be physical change because physical change is when the substance stays the same
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
No, the element remains the same even when the atomic mass changes. Atomic mass is determined by the number of protons and neutrons in the nucleus of an atom, but changing the number of neutrons does not change the identity of the element.
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
it means figure it out yourself!

On heating there will be a change in the physical state not chemical composition. So the number of atoms will be the same even after change in state.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.

The overall mass of a substance remains the same when it changes state. The mass is conserved during physical changes like melting, freezing, vaporization, or condensation. This is because the number of atoms or molecules in the substance does not change during a change in state.
A change that does not make a substance into a new substance is called a physical change. In physical changes, the physical properties of the substance may change, such as shape, size, or state (solid, liquid, gas), but the chemical composition remains the same.
