The atomic number of bromine (Br) is 35, which means it has 35 electrons in its neutral state.

The electron configuration of bromine is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵.

The inner electrons, also known as core electrons, are those in the energy levels below the outermost, or valence, level.

In the case of bromine, the inner electrons are those in the 1s, 2s, 2p, 3s, 3p, 4s, and 3d orbitals.

Counting these up, we have 2 (from 1s²) + 2 (from 2s²) + 6 (from 2p⁶) + 2 (from 3s²) + 6 (from 3p⁶) + 2 (from 4s²) + 10 (from 3d¹⁰) = 30 inner electrons.

So, a bromine atom has 30 inner electrons.
