"Well written ..." That plus keeping things to a reasonable length and on topics intelligible to HS students plus recent enough that you can access them without a time machine makes it a little tough. Best I could come up with are from the 70s, not terribly obnoxious use of passive voice, and actually readable.
J. Phys. Chem., vol. 74, no. 24,1970, pp. 4299-4300.
J. Phys. Chem., vol. 74, no. 23, 1970, pp. 4157-9.
J. Chem. Phys., vol. 21, no. 1. 1953, pp. 80-2.
And more recently, and more accessible
J. Chem. Ed., vol. 71, no. 6, June 1994, pp. 531-3.
Best reading is just browsing JACS from the 30s --- lotsa luck finding a library where it's still on the shelves.
