Question

hypobromite is a polyatomic ion with formula bro⁻. it is produced by the immune system to kill bacteria. how many protons and electrons does a bro⁻ ion contain? protons electrons

Explanation:

Step1: Determine protons in Br and O

Bromine (Br) has atomic number 35, oxygen (O) has atomic number 8. Protons in $BrO^-$ = 35+8 = 43.

Step2: Determine electrons in $BrO^-$

In a neutral atom, number of electrons = number of protons. But $BrO^-$ has a - 1 charge, so number of electrons = 43 + 1=44.

Answer:

43 protons
44 electrons
