ᐉ Trends: Melting Point and Atomic Radius Across Period 3 - Study Mind

WebTrends in Period Three of the Periodic Table. Groups I, II and III are metals and so metallic bonding is used. Group IV is a macromolecule and so has a very large melting point. Groups V, VI, VII are molecules and so we rely on temporary dipole-dipole attractions. Phosphorus is P 4 and so has a reasonably large temporary dipole. WebAcross the period, the atomic radii decrease; This is because the number of protons (the nuclear charge) and the number of electrons increases by one every time you go an element to the rightThe elements in a period all have the same number of shells (so the shielding effect is the same); This means that as you go across the period the nucleus attracts the … low price selling form

Struggling with Chemistry? WebSince the elements are in period 3, this means that all of them have an outer electron in energy level 3. However, the trend has two anomalies. The first is between Mg and Al, because the outer electron of Mg is in the orbital 3s, whereas that of Al is in 3p. The 3p electron has more energy than the 3s electron, so the ionization energy of Al ...
