2 electrons
Electron shell of phosphorus has formula 2, 8, 5. This means that the first layer of its shell holds 2 electrons.
Zinc has 2 electrons on its first energy level.
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.
The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
The first and second energy level will hold maximum of 2 and 8 electrons.
Fluorine has 9 electrons. The first energy level holds 2 electrons, and the second energy level holds 7 electrons. The Bohr model for fluorine would show 2 electrons in the first energy level and 7 electrons in the second energy level.
Each energy level can hold different number of electrons. The first energy level holds 2, second holds 8, and third holds 8. Because the first two energy levels of sodium can only hold 10 electrons, the sodium has a third energy level to hold the 11th electron.
well, on the periodic table of elements a chlorine atom has 17 electrons, usually the first level holds up to two electrons and the second level holds up to 8. so if my figuring is correct there should be fifteen electrons on the second energy level.
Electron shell of phosphorus has formula 2, 8, 5. This means that the first layer of its shell holds 2 electrons.
Two electrons can be housed in the first energy level.
Zinc has 2 electrons on its first energy level.
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
the first energy levels hold 2, 8, and 18 a total of 28 electrons
