Cards in this deck (18)
- 1What does the emission spectra show about electron shells?Electron shells are split into sub-shells.
- 2What are shells labeled using and if it gets bigger what does it mean?labeled using "n" and the further away for the nucleus the less energy associated with shell
- 3What are the maximum number of shells in n = 1, 2, 3, 4?n=1 is 2 electrons
n=2 is 8 electrons
n=3 is 18 electrons
n=4 is 32 electrons - 4What are the subshells titled?s, p, d, f
- 5What are the maximum number of electrons each sub-shell can hold?s = 2
p = 6
d =10
f = 14 - 6What are sub-shells divided into?Orbitals
- 7How many orbitals does an s sub-shell have?one s-orbital that can fit 2 electrons.
- 8How many orbitals does an p sub-shell have?three p-orbitals that can each fit 3 electrons
- 9How many orbitals does an d sub-shell have?5 d-orbitals that can each contain 2 electrons.
- 10How many orbitals does a f sub-shell have?7 f-orbitals that can each fit 2 electrons
- 11Electrons in orbitals have paired spins...they are clockwise and anticlockwise and can only be in the same orbital with opposite paired spins.
- 12What 4 pieces of information are need when describing an electron?Shell, sub-shell, orbital and its spin
- 13What is this?Energies of electron subshells.
- 14Why us 4s lower than 3d?Because 3d subshell had less energy than 4s subshell.
- 15what is this?An s-orbital
- 16What are those?P-orbitals.
- 17what does this show?the arrangement of electrons in atomic orbitals
- 18Oxygen's electron configuration what does it stand for?Big number is the shell, letter is the sub-shell and little number is the number of electrons in orbitals
