electronic structure

Question 1

what are electrons arranged on?

Answer 1

priniciple energy levels numbered 1, 2, 3, 4… 1 is closest to the nucleus

Question 2

how many electrons does s sub shell hold?

Answer 2

2

Question 3

how many electrons does p sub shell hold?

Answer 3

6

Question 4

how many electrons does d sub shell hold?

Answer 4

10

Question 5

how many electrons does f sub shell hold?

Answer 5

14

Question 6

what are orbitals?

Answer 6

hold up to 2 electrons with opposite spins

Question 7

what is the shape of an s sub shell

Answer 7

spherical

Question 8

what is the shape of a p sub shell?

Answer 8

dumbbells

Question 9

what impacts the shapes of orbitals

Answer 9

mathematical probabilities of finding an electron at any point within certain spatial distributions around the nucleus

Question 10

how do atoms fill up the sub shells?

Answer 10

in order of increasing energy, and they fill each orbital singly before starting to pair up the electrons

Question 11

why does 3D get filled after 4S?

Answer 11

3D is higher in energy than 4s and so gets filled after the 4s
