Electrons Question?

Question

The reason that the 11th electron of the sodium atom is located in the third energy level rather than the second energy level is that the second energy level can only hold a maximum of how many electrons?

- my answer is 3electrons, correct me if i'm wrong please!

Answer 1

The lowest level holds 2, the next (2nd) level holds 8, so the 11th electron has to go into the 3rd level

Answer 2

absolutely not, the first energy level can hold 2, the second holds 8, the third holds 18, the fourth holds 32, and so on and so forth. the electron configuration for sodium is 1s2, 2s2, 2p6, 3s1

Answer 3

i do no longer understand in case you recognize sufficient relating to the actual shape of atoms for this answer. All atoms have electrons - one for each proton in its nucleus (you recognize that the electrons orbit the nucleus, precise?). properly, the on the instant familiar sort of the form of atoms has the electrons occurring in orbit clouds around the nucleus yet at particular distances from the nucleus (called "shells") in accordance with how many there are for that atom. The valence electrons are those interior the outer-maximum "shell" of electrons and that they verify the electrical powered fee (if any) of the atom in question and what it extremely is bonding potential would be (i.e. the way it is going to react or connect with different atoms). that's as non-technical as i'm able to declare it without getting all physics-y on you.
