Bromine (Br) has 18 core electrons. This can be determined by subtracting the number of valence electrons (7 in the case of bromine) from the total number of electrons in a neutral atom, which is 35 for bromine.
Helium has 2 core electrons. This is because it has 2 electrons in the innermost energy level (K shell), which are considered core electrons.
Hydrogen has one core electron. Core electrons are those in the inner energy levels of an atom and are not involved in chemical bonding.
Argon has 18 core electrons. This is because the atomic number of argon is 18, and the number of core electrons is equal to the number of electrons in the nearest noble gas configuration, which in this case is neon (10 core electrons), plus the number of electrons in the next energy level, which is 8 for argon.
28 electrons Nickel atoms have 28 electrons and the shell structure is 2.8.
Titanium has 10 core electrons, which are the electrons in the inner energy levels that are not involved in chemical bonding. The electron configuration of titanium is 1s2 2s2 2p6 3s2 3p6 4s2 3d2.
Bromine (Br) has 35 electrons in total. It has 7 valence electrons (outermost shell) and 28 core electrons (inner electron shells).
To be neutral, Bromine (atomic symbol Br) has 35 electrons. Ions have more or less.

The neutral atom has 35 electrons.
Germanium has 36 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding.
Oxygen has 6 core electrons.
Tin has 46 core electrons.
Eight electrons in the 2nd shell of Br- This is also the number of electrons in the 2nd shell of I-, Cl- and even F- !
The anion is Br+; bromine has 7 valence electrons.
Germanium has 18 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Oxygen as 2 core electrons and 6 valence electrons.
Carbon has 2 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
