QuestionHow many electrons does bromine (Br\mathrm{Br}) have? Options: 34, 7, 4, 36.

Studdy Solution

STEP 1

Assumptions1. We are looking for the number of electrons in a neutral atom of bromine (Br). . The atomic number of bromine is35.

STEP 2

The number of electrons in a neutral atom is equal to the atomic number. This is because in a neutral atom, the number of electrons (negative charge) equals the number of protons (positive charge) to balance out to a neutral charge.
Numberofelectrons=AtomicnumberNumber\, of\, electrons = Atomic\, number

STEP 3

Now, plug in the atomic number of bromine to calculate the number of electrons.
Numberofelectrons=35Number\, of\, electrons =35So, a neutral atom of bromine has35 electrons.
