All atoms of the same element are not identical! This paradox of atomic structure is due to the existence of isotopes—atoms of the same element having different masses. In this hands-on activity, students investigate the mass and relative abundance of three isotopes for the “bean bag” element, Bg, and then calculate Bg’s atomic mass. Students will gain a clear understanding of the relationship between the atomic mass of an element and the mass of each isotope. Kit includes reproducible student handouts, detailed background information, and teacher notes with sample data and answers to questions.
Complete for a class of 30 students working in pairs.
