Using only the following elements P, Br, and Mg, give the formulas for:A. an ionic compound. B. a molecular compound with polar covalent bonds that obeys the octet rule and has no formal charges.

Explanation:

Mg is a metal that has 12 atomic numbers and thus its electronic configuration is . The outer most shell of this element has 2 electrons so it loses 2 electrons and thus form ions. Br is a nonmetal and has 35 atomic number so its electronic configuration is . Since its outermost shell has 7 electrons so it can accept one electron and thus forms . So magnesium ion and bromide ion combine and forms an ionic compound .

P is also a nonmetal and combine with Br with covalent bond and due to electronegativity differences form polar covalent compound such as .

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
