Chemical vs Nuclear Day 2 Guided Notes Name: _______________________________ Four Fundamental Forces (strong weak) _____________________ force : holds middle of atom (protons/neutrons) _____________________ force : holds electrons __________________ force : causes some forms of radioactivity; atomic decay _____________________ : causes all things with mass to attract Nuclear vs. chemical reactions Nuclear reactions result in ___________________ (nucleus combining) or _______________________ (nucleus fusing). Chemical reactions result in the atoms _____________________________ or _____________________________. What is RADIOACTIVITY? Radioactive ____________ occurs in unstable atomic nuclei –due to an excess of either protons or neutrons. This unstable nucleus will then _________________________ energy or a particle known as radiation Alpha Decay If an atom releases an alpha particle, it will be ______________________ (proton) charged. Mass number decreases by _____________ and atomic number decreases by ____________ units. Beta Decay If an atom releases a beta particle, it will be _______________ (electron) charged. Mass number ___________________________ and atomic number increases by _______________ unit. Gamma Decay If an atom releases a gamma particle, it will have _______________________ (neutron). Mass number ________________________ and atomic number ___________________________.
