Determining the number of valence electrons
WebFor this, iron ion (Fe 2+) has a total of fourteen valence electrons. Again, the iron atom donates two electrons in the 4s orbital and an electron in the 3d orbital to convert an iron ion (Fe 3+ ). Fe – 3e – → Fe 3+. Hare, the … WebYou can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table. For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively. Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively. Valence electrons are responsible for the reactivity of an element.
