28 electrons
Nickel atoms have 28 electrons and the shell structure is 2.8.
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.
Ni3+ has 23 electrons. This is because Nickel (Ni) normally has 28 electrons, but when it loses 3 electrons to become Ni3+, its electron count decreases to 23.
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.
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.
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.
Oxygen has 6 core electrons.
Argon has 18 core electrons. This is because it has 18 electrons in total, and the core electrons are the innermost electrons that are not involved in chemical bonding.
Helium has 2 core electrons. This is because it has 2 electrons in the innermost energy level (K shell), which are considered core electrons.
Silicon has a total of 10 core electrons and 4 valence electrons.
Nitrogen has 2 core electrons. Core electrons are those that are found in the inner energy levels and are not involved in chemical bonding.
Tungsten has 46 core electrons. Core electrons are the electrons found in all elements that are not valence electrons. Tungsten has an atomic number of 74, so it has 74 electrons in total.
