Sn (tin) has 50 electrons 50 protons and 69 nuetrons
Carbon has 2 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Nitrogen has 2 core electrons. Core electrons are those that are found in the inner energy levels and are not involved in chemical bonding.
Helium has 2 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Bromine has 28 total electrons, with 18 being core electrons located in the inner electron shells.
Neon (Ne) has 10 core electrons. Core electrons are the electrons in an atom that are not involved in chemical reactions. For neon, the core electrons are the 1s²2s²2p⁶ electrons, which total 10.
Tin has 46 core electrons.
Sn has 50 total electrons and is in the Group 4a elements on the periodic table. The nearest Noble Gas that is before Sn is Kr, which has 36 electrons. Therefore, the number of inner electrons (the same as Kr's electrons) is 36, outer electrons is 4 and valence is 4 as well (because its a Group 4a
Germanium has 36 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding.
Oxygen has 6 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.
An atom of Sn (Tin) has 4 valence electrons in the 5th shell, so it has 4 p 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.
