Don't confuse with

陽よう子し
陽子 (proton) carries a positive charge and sits in the nucleus alongside the electrically neutral 中性子 (neutron), so learners often mix up which particle has which charge.
電でん子しN2
電子 (electron) orbits outside the nucleus and is much lighter, while 中性子 (neutron) is a heavy particle found inside the nucleus, so the two are easy to confuse when learning basic atomic structure.
