What is the maximum number of electrons the first energy level will hold?

Answer 1

The number of electrons in the lowest electron shellis

2 in the first or K shell (subshell 1s)

---

For other shells, the maximum is determined by the formula 2n2:

2) 8 in the L shell (subshells 2s, 2p)

3) 18 in the M shell (subshells 3s, 3p, 3d)

4) 32 in the N shell (subshells 4s, 4p, 4d, 4f)

5) 50 in the O shell (subshells 5s, 5p, 5d, 5f, 5g*)

6) 72 in the P shell (subshells 6s, 6p, 6d, 6f, 6g, and an unnamed subshell)

7) 98 in the Q shell (subshells 7s, 7p, 7d, 7f, 7g, and two unnamed subshells)

* the highest existing subshells are 5f, 6d, and 7s

* the highest currently predicted subshells are 7p and 8s

* no existing element has more than 32 electrons in any shell

The maximum per subshell is determined by the formula 2(2L+1) (s is 0):

s subshells can have 2 electrons

p subshells can have 6 electrons

d subshells can have 10 electrons

f subshells can have 14 electrons

g subshells can have 18 electrons

*There are no elements with electrons past the f subshell, so the shells with 22 and 26 electrons have no name. The largest element created (Roentgenium, element 111) has 2 electrons in the 7s shell.

Answer 2

Eight. To find out, simply turn to the Periodic Table of the elements. In Group 18, the last, or maximum group (the noble gases) have 8 electrons in their first energy level. That is also why they are the least reactive substances: They don't exchange electrons with other atoms (otherwise known as a chemical reaction).

Answer 3

2

then 8

then 8

Continued...

It goes 2 at the first energy level but then continues at 8.

Answer 4

The first shell can only hold 2 electrons in it.

Answer 5

the first energy level can only hold 2

Answer 6

2

Answer 7

Two
