Radium (Ra) has 20 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding and are not part of the valence shell. In the case of radium, the core electrons would include those in the first three energy levels, up to and including the electron configuration [Xe] 6s1.
Germanium has 36 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding.
Germanium has 18 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
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.
Cadmium (Cd) has 48 electrons, and its electron configuration is [Kr] 4d10 5s2. This means that the core electrons in cadmium are those in the inner shells, which are the 36 electrons from the noble gas krypton (Kr). Therefore, cadmium has 36 core electrons.
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.
There are 86 core electrons in radium (Ra), which is the number of electrons in filled inner electron shells. Radial's electron configuration is [Rn] 7s2, where [Rn] represents the electron configuration of radon (Rn) as the previous noble gas element.
Radium has 86 electrons.
Germanium has 36 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding.
Germanium has 18 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
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.
Carbon has 2 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Silicon has a total of 10 core electrons and 4 valence electrons.
it has 2 electrons i think you can tell by subtracting both numbers together
Helium has 2 core electrons. This is because it has 2 electrons in the innermost energy level (K shell), which are considered core electrons.
Cadmium (Cd) has 48 electrons, and its electron configuration is [Kr] 4d10 5s2. This means that the core electrons in cadmium are those in the inner shells, which are the 36 electrons from the noble gas krypton (Kr). Therefore, cadmium has 36 core electrons.
Oxygen as 2 core electrons and 6 valence electrons.
Oxygen has 6 core electrons.
