shells and orbitals

Question 1

arrangement of electrons in atom is called

Answer 1

electron configuration

Question 2

electrons arranged in

Answer 2

principle energy levels

Question 3

what are principle quantum numbers (n) used for

Answer 3

number energy shells

Question 4

lower principle quantum number

Answer 4

closer the shell is to the nucleus (so first shell is n=1)

Question 5

number of fixed electrons it can hold

Answer 5

n=1: 2 electrons
n=2: 8 electrons
n=3: 18 electrons
n=4: 32 electrons

Question 6

what are principal quantum shells split into

Answer 6

subshells

Question 7

what are the subshells

Answer 7

s,p,d,f

Question 8

energy of electrons in subshells order

Answer 8

s<p<d<f

Question 9

what is an orbital

Answer 9

found at a specific energy level and can hold up to 2 electrons

Question 10

s subshell number of orbitals and electrons

Answer 10

1 orbital
2 electrons

Question 10

p subshell number of orbitals and electrons

Answer 10

3 orbitals
6 electrons

Question 11

d subshell number of orbitals and electrons

Answer 11

5 orbitals
10 electrons

Question 12

f subshell number of orbitals and electrons

Answer 12

7 orbitals
14 electrons

Question 13

s orbital shape

Answer 13

spherical, size increases with shell number

Question 14

p orbital shape

Answer 14

dumbbell shape, occupy the x,y and z axis at right angles to each other so are orientated perpendicular to each other,
lobes become larger and longer with increasing shell number

Question 15

what is ground state

Answer 15

the most stable electron configuration which has the lowest amount of energy
