How to calculate atomic mass and number

Protons

• I am the postivie particel of the atom
• I also give elements their idenity
• I weigh 1 amu
• I live inside the nucleus

Back to activity

Neutrons

• I am neutral charge
• I help give the element its mass
• I have a mass of 1 amu
• I also make different types of the same element called isotopes by changing its mass
• You can calulate me by subtracting the atomic mass of the element by the number of protons!

Electrons

• I am negatively charged
• I live outside the neucleus
• I give the element the ability to react
• I give the element charge and the ability to bond
• My mass is 0 amu because my mass is so tiny
