8 electrons.
Second shell has a maximum of 8 electrons.
In sodium, the second shell (or energy level) can hold a maximum of 8 electrons. However, sodium only has 2 electrons in its second shell. Sodium has an atomic number of 11, so it has 11 electrons in total, with 2 in the first shell and 8 in the second shell.
A complete valence shell typically holds 8 electrons. However, for elements in the first two rows of the periodic table, the valence shell can hold a maximum of 2 electrons in the first shell and 8 electrons in the second shell.
The second shell can hold eight electrons.
Carbon has 4 electrons on its second shell. This is calculated based on the maximum number of electrons that can occupy the second shell, which is 8.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Sulfur (S) has 6 electrons in its outermost shell and 2 electrons in its innermost shell, but the next shell also has 6 electrons, making it an example of having more than one shell occupied by electrons while still having the same number of electrons in each shell.
Neon - Ne From the periodic table
Their outermost electrons are in the same shell. For example, Helium and Hydrogen have 1 and 2 electrons respectively, and these electrons exist within the first electron shell. Lithium has 3 electrons and the third of these electrons is in the second electron shell, and so, it is a member of the 2nd period of the periodic table.
number of electrons in the bonding shell vary according to the element. for example group 1 in the periodic table contains elements with ony one electron in their bonding shell, similarly group 2 has elements with two electrons in its bonding shell and so on. the group number in the periodic table denotes the number of electrons in the bonding shell of each element present in that particular group
Oxygen has a proton number of 8, meaning that it has 8 electrons. The electronic structure of oxygen is 2.6 This means that the number of electrons in the second shell is 6.
Hafnium may be found in column 4 of a wide form periodic table. This indicates that it has four valence electrons.
