Electron Questions

• Are two atoms of the same element identical?
• Can the decay half-life of a radioactive material be changed?
• Could electronic devices charge themselves without being plugged into an electricity source?
• Do atoms ever actually touch each other?
• Does a source of electricity ever run out of electrons?
• Does an electron in an atom move at all?
• How can an electron leap between atomic levels without passing through all the space in between?
• How can radioactive decay just happen with nothing triggering it?
• How does dissolving a salt molecule in water make its atoms ionize?
• What is the shape of an electron?
• What is the speed of electricity?
• Why do atoms always contain the same number of electrons and protons?
• Why don't atoms collapse if they are mostly empty space?
• Why don't electrons in the atom enter the nucleus?
• Why were electrons chosen to be negatively charged? Wouldn't it make more sense to call electrons positively charged because when they move they make electricity?
