need help on this! 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.

a corroding iron, if that's one of your choices

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is
