En aquesta pr\u00e0ctica, l’alumnat de 4t va con\u00e8ixer els diferents colors de les radiacions emeses per alguns \u00e0toms al metall. Despr\u00e9s d’estudiar la taula peri\u00f2dica i l\u2019estructura dels \u00e0toms, han pogut comprovar com els electrons es mouen entre diferents nivells energ\u00e8tics.<\/p>\n

Quan les sals met\u00e0l\u00b7liques es posen a la flama, emeten llum de diferents colors, caracter\u00edstics de cada metall. Aquest procediment s\u2019anomena assaig a la flama.<\/p>\n

Aix\u00f2 passa perqu\u00e8 els electrons excitats dels \u00e0toms tornen al seu estat fonamental generant una\u00a0 emissi\u00f3 de radiaci\u00f3 electromagn\u00e8tica, corresponent al salt entre dos nivells d’energia. L’explicaci\u00f3 al fenomen la podem trobar en el model at\u00f2mic de Bohr.<\/p>\n
