High-school and undergraduate college students {may|might|could|may possibly|may well|may perhaps} {often|frequently|usually|typically|generally|normally} {rely on|depend on} memorization when {learning|studying|understanding|finding out|mastering} periodic trends, {leading|top|major} to an ineffective understanding of introductory chemistry {concepts|ideas} like atomic radius, ionization {energy|power}, and electron affinity. Comprehension of {effective|efficient|successful|powerful|productive|helpful} nuclear charge (Zeff) is foundational to a {complete|total|full|comprehensive} understanding of periodic trends. Zeff remains an abstract {concept|idea|notion} {for many|for a lot of} students, indicating that a manipulative activity for teaching the phenomenon {could be|might be|could possibly be|may be|may very well be} a {useful|helpful|beneficial|valuable} {way to|method to|approach to|strategy to|technique to|solution to} {explain|clarify} the {concept|idea|notion} for {greater|higher} student comprehension. {Here|Right here} we report a hands-on {learning|studying|understanding|finding out|mastering} activity to target this {knowledge|understanding|information|expertise|know-how} gap {using|utilizing|making use of|employing|working with|applying} magnetic attraction as an analogy for electrostatic attraction {within the|inside the} atom. This {approach|method|strategy} enables students to {explore|discover} the phenomenon of {effective|efficient|successful|powerful|productive|helpful} nuclear charge at a macroscopic level and apply their {learning|studying|understanding|finding out|mastering} to periodic trends and {related|associated|connected} {concepts|ideas}. We anticipate that this activity will fill a long-standing hole {in the|within the|inside the} active {learning|studying|understanding|finding out|mastering} of chemical principles. Importantly, this activity is low-cost {and can|and may} be assembled {using|utilizing|making use of|employing|working with|applying} readily accessible {materials|supplies|components} to {allow|permit|enable|let} implementation in most classrooms and virtual {learning|studying|understanding|finding out|mastering} environments. 2,3,4,5,6-Pentafluorostyrene site Price of 109705-14-8 PMID:34856019
