For each compound, write the cation and anion with the appropriate charge. Then write the chemical formula for each compound. Example: sodium fluoride: Na+1, F-1 NaF
a. Magnesium oxide
b. Strontium iodide
c. Aluminum chloride
d. Calcium phosphide

Esign techniques and materials that reduce the negative environmental impact of a structure are referred to as

16. why must the number of electrons lost equal the number of electrons gained in every redox reaction? use 3 – 4 sentences in your own words to address this question. 18. what type of radiation is emitted when chromium-51 decays into manganese-51? show the nuclear equation that leads you to this answer. 19. a radioactive nucleus alpha decays to yield a sodium-24 nucleus in 14.8 hours. what was the identity of the original nucleus? show the nuclear equation that leads you to this answer.

Question 3(multiple choice worth 4 points) (04.04 lc) what does it mean when an element is reduced? it empties a valance shell, reducing its atomic radius. it gains electrons, reducing its overall charge. it increases electronegativity, reducing its ability to bond. it loses electrons, reducing its electron number.
