Protons! :)
Radioactive decay is the process by which a mineral spontaneously changes into subatomic particles.
It is a property, like mass. Not a particle. The electron and proton charges are considered to be the reference charges (-e and +e).
everywhere Anything having the property of mass has inertia, so except for a few exotic subatomic particles, everything has the property of inertia.
Electric charge is a property that causes subatomic particles such as protons and electrons to attract or repel each other. Particles with opposite charges (e.g. positive and negative) attract each other, while particles with the same charge (e.g. positive and positive) repel each other.
Particle is not a property; a particle is a form of a material, small size.
Atomic Mass units
Isotopes differ each other from the number of neutrons which is a chemically inert subatomic particle.
Yes, melting point is a physical property, not a chemical property. It is a characteristic of a substance that can help identify and differentiate it from other substances based on how it changes states from solid to liquid.
Charge is a property of subatomic particles like protons and electrons, which are present in all atoms. All atoms contain some combination of positively charged protons in the nucleus and negatively charged electrons orbiting the nucleus. This gives atoms an overall neutral charge, but they do have individual charges on their component particles.
No, an electron is a fundamental particle that is not a chemical property. Chemical properties describe the behavior of substances in chemical reactions, while electrons are subatomic particles that contribute to the structure of atoms and molecules.
A physical property.
There really isn't one single property, there are multiple properties that need to be used to diagnose a mineral.
