Question

Quizplus · Accepted Answer

The identity of an element is determined by the number of protons in its nucleus, as this defines the atomic number. The phase of matter (solid, liquid, gas, or plasma) is primarily determined by temperature, which affects the kinetic energy of the atoms or molecules, leading to changes in phase.
