Answer:

1. Ionic compound- $MgBr_2$

2. Polar molecular compound- $PBr_3$

Explanation:

Magnesium (Mg), with atomic number 12, has an electron configuration of $1s^22s^22p^63s^2$ . The outermost shell possesses 2 electrons, thus it loses these 2 electrons to become $Mg^2^+$ ions. Bromine (Br), a nonmetal with atomic number 35, has an electron configuration of $1s^22s^22p^63s^23p^64s^23d^1^04p^5$ . Its outermost shell holds 7 electrons, allowing it to accept one electron and thus forms $Br^-$ . Hence, the magnesium ion and bromide ion bond together to form an ionic compound $MgBr_2$ .

Phosphorus (P), also a nonmetal, bonds with bromine covalently. Due to differing electronegativities, they produce polar covalent compounds like $PBr_3$ .
