Which of the following is the best name for a compound made from calcium and bromine? (cabr2) calcium bromide calcium dibromide monocalcium dibromide calcium bromine ii

Calcium bromide

Explanation:

When naming compounds, the use of prefixes depend on the type of bond made. In this case, calcium and bromine form a ionic bond because calcium is a metal and bromine is a non-metal.

Ionic bonds are not named using prefixes. So no matter how many atoms there are, you will simply write the name of the element for the first element.

For the second element, you name it as well, but only use the root name and end it with -ide.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
