About This Product
Teachers begin by pointing out the central region that stands for the nucleus, then explain the charge carried by each particle. From there the model leads into atomic number, which is set by the proton count, isotopes, which differ in neutron number, and ions, which form when electrons are gained or lost. It prepares students for later work on electron configuration and chemical bonding.
Frequently Asked Questions
Q1. What decides an element's atomic number? The number of protons in the nucleus. Atoms of one element always have the same proton count, while their neutron number can differ, which is what produces isotopes.
