Question

which is a tiny negatively charged subatomic particle movir outside the nucleus of an atom? electron neutron compound proton is any of the possible energies an electron may h atom. electron energy levels compound valence electrons

Explanation:

• First question:
• An electron is a subatomic particle with a negative charge that moves outside the nucleus of an atom.
• A neutron is a neutral subatomic particle located in the nucleus.
• A compound is a substance formed from two or more elements chemically bonded, not a subatomic particle.
• A proton is a positively - charged subatomic particle in the nucleus.
• Second question:
• Energy levels refer to the possible energies an electron may have in an atom.
• An electron is the particle itself, not the energy it may have.
• A compound is a substance, not related to electron energies.
• Valence electrons are the electrons in the outermost energy level, but the term for the possible energies is energy levels.

Answer:

First question: Electron
Second question: Energy Levels
