Period 3 highest melting point
WebDec 19, 2024 · There is a list of high melting point elements as follows: What should the melting point be in period 3? Strictly speaking it should be 273.15 rather than 273, but the less precise value is acceptable at A Level. The graph shows how melting points and boiling points vary across period 3. WebSo in periods two and three, the highest melting point elements tend to be the metal elements with the most delocalized electrons. For the elements given, the metal element that has the most delocalized electrons is beryllium. So the correct answer is (B). Beryllium is the …

WebMelting and boiling point: they tend to rise up to about group 3 or 4, before falling rapidly after that. I would suggest that this is because group 4 elements tend to have giant covalent structures, so also a higher boiling point, whereas on the right hand side of a period they are simple molecular structures, so have a low boiling point.
