Part 1: Isotopes

Click on the 'Isotopes' tab in the simulation below. Use the simulation to answer questions 4-11.

(If you'd like to have the simulation open in another tab, visit Isotopes and Atomic Mass PhET)

Pitanje 12
12.

Build an atom of Hydrogen-1, Hydrogen-2, and Hydrogen-3.

What does the number (-1, -2, or -3) in the isotope name represent (hint: what does adding neutrons effect at a glance)?

Pitanje 13
13.

Build a Hydrogen-1 isotope. Click between the 'Mass Number' and 'Atomic Mass (amu)' options on the scale. Do the same thing but by building a Hydrogen-2 isotope.

Match the numbers below.
