Flashcards do conjunto (12)
- 1Number of Electrons that fill up the first 4 energy levels?1st Shell = 2
2nd Shell = 4
3rd Shell = 18
4th SHell = 32 - 2Formula of Max number of electrons in a Shell2n²
- 3What is an Atomic Orbital ?Region around nucleus that can hold up to 2 e- with opposite spins
- 4What types of Orbitals are there?s orbital
p orbital
d orbital
f orbital - 5Shape and Properties of an S-orbital?Sphere, hold 1-2 e-
~ Each shell contains 1 S-orbital
~ Greater the shell number, greater the S-orbital radius - 6Shape and Properties of an P-orbital?Peanut, holds 1-2 e-
~ Each shell (from 2) contains 3 P-oritals, at 90 degrees to each other
~ Greater the shell number, further P-orbital is from nucleus - 7Shape and Properties of an D and F -orbital?d-orbital
~ Each shell (from 3) contains 5 d-orbital
~ 2 e- in each orbital
f-orbital
~ Each shell (from 4) contains 7 f-orbital
~ 2 e- in each orbital - 8What happens when a new shell is added?~ new orbital appears
~ number of orbitals increases
~ number of e- in each subshell increases - 9Name the subshell in increasing energy level (distance from the nucleus)1s, 2s 2p, 3s 3p 4s, 3d 4p 4d 4f
4s fills before 3d - 10Why must two e- in an orbital have opposite spins ?Opposite spins help to counteract the repulsion between the negative charge of the 2 e-
- 11What is shorthand e- configurationusing noble gas + the outer electron configuration
Useful for showing similarities in e- configuration of outer shells - 12Electron configuration for Li(3), Be(4), B(5), C(6), N(7), O(8), F(9), Ne(10)Li- 1s² 2s¹
Be- 1s² 2s²
B- 1s² 2s² 2p¹
C- 1s² 2s² 2p²
N- 1s² 2s² 2p³
O- [He] 2s² 2p⁴
F- [He] 2s² 2p⁵
Ne-2s² 2p⁶
