If your students can calculate the number of protons, neutrons and electrons in an atom, they will be rewarded with a magic picture of a snowman in a snow globe!
As each question is answered correctly, more pixels of the image are revealed. Self checking – if no pixels are revealed, you’ve made a mistake!
Types of questions include:
How many protons in an atom with atomic number 9 and mass number 19?
What is atomic number of atom with 6 protons, 6 electrons, and 7 neutrons?
How many neutrons in an atom with atomic number 9 and mass number 21?
How many electrons in an atom with atomic mass 8 and mass number 18?
