I have to write about this is my work Your friend, who has been studying asteroids, has encountered an element they cannot identify. This element has several unique characteristics. It is a brittle solid at room temperature and not very reactive. After experimenting on the element, they were able to determine that the atomic mass was at least 30 and no higher than 33. The element also has valence electrons in the third energy level. Looking at the periodic table below, answer the following questions in CER format: What could be the identity of this element? There is more than one correct answer.
