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. This oxide dissolves in water to form an acidic solution. (i) Deduce the type of bonding in this oxide of X. WebK = °C – 273 (e.g. 273 K = 0 °C) Strictly speaking it should be 273.15 rather than 273, but the less precise value is acceptable at A Level.
