Electron Arrangement Flashcards
1
Q
What are Atomic Orbitals
A
Region around the nucleus that can hold 2 electrons with opposite spins (up or down)
2
Q
Shape, number and shell of S orbital
A
circular. Only 1. In all 4 shells
3
Q
Shape, number and shell of P orbital
A
Dumbbell shape. 3 P orbitals. In only 3 shells
4
Q
Number and shell of d orbital
A
5 D orbitals. Only in shells 3 and 4
5
Q
Number and shell of f orbital
A
7 F orbitals. In shell 4 and above
6
Q
What happens to the energy in the shells as we move away from the nucleus
A
increases
7
Q
Why do we put electrons into individual orbitals instead of orbitals with the same energy
A
Because electrons in the same orbitals repel each other
