1fundamental particles- charge of a neutron and the relative mass
- Amass 1 charge 1
- Bmass 0 charge 1
- Cmass 1 charge 0
- Dmass 1 charge -1
2relative mass of an electron
- A1/1840/0.911 x 10-30
- B1/1940/0.911 x 10-30
- C1/ 1.673 x 10-27
- D1/ 1.773 x 10-27
3what is the protons and neutrons held together with in the nucleus? which force?
- Astrong nuclear force
- Belectrostatic force
- Cmicro gravity
- Dstrong atomic force
- Enuclear fusion
4what force keeps the electrons orbiting the nucleus and is it strong or weaker that the force in question 3?
- Aelectrostatic, weaker
- Bgravity, stronger
- Cgravity, weaker
- Delectron attraction, weaker
5sub-shells, what is the correct sub-shell arrangement for an atom with four shells?
- A1s, 2p, 3d, 4f
- B1s, 2p, 3d, 4q
- C1s, 2s, 2p, 3s, 3p, 4s, 3d
- D1s, 2s, 2p, 3s, 3p, 3d, 4s
6how many electrons can you have on each shell?
- Ashell 1 = 2
shell 2 = 8
shell 3 = 18 - Bshell 1= 2
shell 2 = 8
shell 3 = 10 - Cshell 1 =2
shell 2 = 8
shell 3 = 8 - Dshell 1= 2
shell 2= 10
shell 3 = 18
- Ashell 1 = 2
7how many electrons in each sub shell?
- As= 2
p= 6
d= 10 - Bs= 2
p= 8
d= 10 - Cs= 2
p= 8
d = 15 - Ds= 1
p= 3
d= 5
- As= 2
8electrons come in pairs? but will only pair when they have to, eg 3 electrons on the 2nd shell wont pair but 4 electrons would have one pair two not paired
