Radicals in Molecular Structure Notation

[Douglas Nguyen 2J]

For the "ABE" notation (A being the central atom, B being atoms bonded to the central atom, and E being lone electron pairs around the central atom), how is it written for radicals?

ex: "4.19 Predict the shapes and estimate the bond angles of...(c) BH(2)-"

BH(2)- has only 5 electrons, so boron carries a single electron. How would the ABE notation be written in this instance?

I think BH2- has 6 electrons. B has 3, H2 has 2, and since it has the - charge it adds another electron, adding up to 6.
So the VSEPR formula would be AX2E1.

LOL I cannot do math. I'm leaving this school.
