Nitrogen has 2 core electrons. Core electrons are those that are found in the inner energy levels and are not involved in chemical bonding.
it has 2 electrons i think you can tell by subtracting both numbers together
2,8,18,7... 28 core electrons 7 valence electrons.
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.
there are 12 electrons in carbon. you can find this out by looking at the "ATOMIC NUMBER"
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Germanium has 36 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding.
Hexane has 42 electrons. Each carbon atom in hexane has 6 electrons (4 valence electrons and 2 core electrons), and each hydrogen atom has 1 electron.
Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
Sulfur. It has six valence electrons. These six electrons plus the ten core electrons, 16, the atomic number (number of electrons or the number of protons [they are an equal amount because the positive and negative charges have to cancel each other out]). It is sulfur.
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.
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.
