electron structure

Question 1

which shells have which sub shell

Answer 1

1 has s
2 has s and p
3 has s p and d
4 has s p d and f

Question 2

formula for the number of electrons in each shell

Answer 2

2n^2

Question 3

what are orbitals

Answer 3

region around the nucleus that can hold 2 electrons with opposite spins

Question 4

what is the shape of a s orbital

Answer 4

sphere

the grgester the shell number the greater the radius

Question 5

shape of p orbital

Answer 5

dumbbells

Question 6

how many orbitals and electrons does each orbital have

Answer 6

s has 1 orbital and 2 electrons
p has 3 orbitals and 6 electrons
d has 5 orbitals and 10 electrons
f has 7 orbitals and 14 electrons

Question 7

how do atoms fill up with electrons

Answer 7

in sub shells in order of increasing energy

Question 8

what are the 2 rules for all orbitals with the same energy

Answer 8

electrons wont pair in the same orbital if they dont have to
electrons in the same orbital must have opposite spins to avoid repulsion
