• Protons (+): Atomic Number
• Neutrons: Atomic Mass minus Protons
• Electrons (-): Same number as Protons
• Protons (+): Atomic Number
• Neutrons: Atomic Mass minus Protons
• Electrons (-): Same number as Protons

What is amu????• amu is short for atomic mass unit
• 1 amu = 1.66053886 × 10-27 kilograms
• EXAMPLE: If you weigh 150 lbs, what is that in kilograms?
1 kg = 2.2 lbs
150 lbs2.2 lbs
68.2 kg1 kg
• EXAMPLE: If you weigh 150 lbs, what is that in amu?
68.2 kg1.66 x 10-27 kg
1 amu4.11 x 10+28 amu
