WebWe will now discuss the trend in melting points across Period 3: 1. The change in melting point from Sodium to Aluminium (Na to Al). Sodium, magnesium and aluminium are all metals and therefore have metallic bonding. As well learned earlier, the more delocalised electrons present and the smaller the radius of the atom, the higher the melting ... WebPeriod 3 metal chlorides tend to have high melting points while non-metal chlorides have low melting points. The metal chloride AlCl 3 is an anomaly and has a low melting point. …
WebPeriod 3 SCT Page 1 of 17 Q1. This question is about the elements in Period 3 from sodium to phosphorus (Na to P) and their oxides. (a) Element X forms an oxide that has a low melting point.
