Which of the following is true about the compound mgbr2? question 2 options: a magnesium atom gained 2 electrons, while two bromine atoms each lost 1 electron. a magnesium atom lost 2 electrons, while a bromine atom gained 2 electrons. a bromine atom lost 2 electrons, while a magnesium atom gained 2 electrons. a magnesium atom lost 2 electrons, while two bromine atoms each gained 1 electron.

We have to get true statement about the compound MgBr₂.

The true statement is: a magnesium atom lost 2 electrons, while two bromine atoms each gained 1 electron.

Magnesium is electropositive element while bromine in electronegative element. Magnesium releases electron and bromine accepts electron.

Magnesium can release two electrons and gets outermost shell fulfilled whereas each bromine accepts one electron to get outermost shell fulfilled. So, two bromine atoms combine with one magnesium atom.

Magnesium can not accept electron and bromine can not release electron.

answer: c.

explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
