Explanation:

Bromine is a group 17 element and contains 7 valence electrons. And, in order to completely fill its octet it needs to gain just one electron. When it chemically combines with another substance and forms a compound with chemical formula as $XCl_{2}$ then it means charge on substance X is +2.

For example, compound formed between magnesium and bromine is magnesium bromide and its chemical formula will be $MgBr_{2}$ .

Any element of group 2 can react with bromine to form a compound with chemical formula $XBr_{2}$ .

Why is phosphorus unusual compared to other group 15 elements? Select the correct answer below: A. There are compounds that cont

luda_lava [24]

Answer:

There are compounds that contain phosphorus-phosphorus bonds with uncommon oxidation states.

Explanation:

Phosphorus is a member of group 15 in the periodic table. Its common oxidation States are -3 and +5. Phosphorus is believed to firm some of its compounds by the participation of hybridized d-orbitals in bonding although this is also disputed by some scientists owing to the high energy of d - orbitals.

Phosphorus form compounds having phosphorus-phosphorus bonds in unusual oxidation states such as diphosphorus tetrahydride, H2P-PH2, and tetraphosphorus trisulfide, P4S hence the answer.
