Electron Structure Flashcards
How many electrons does the fourth shell hold?
32
What is the definition of the first ionisation energy?
The energy required to remove an electron from each atom in a mole of gaseous atoms to form one mole of gaseous 1+ ions
How many electrons does the third shell hold?
18
What is an oribital?
An area of an atom that can hold a maximum of two electrons with opposite spin
What shape is an s orbital?
Spherical
How many electrons does the second shell hold?
8
What shape is the p orbital?
Dunbell/figure of eight
How many electrons does s subshells hold?
2

10
How many orbitals does a d subshell have?
5
How many electrons does the first shell hold?

What are the three factors affecting ionisation energy?
Distance-increasing distance between nucleus and electrons means there is less attraction for electrons so ionisation energy decreases
Nuclear charge-increasing the number of protons in the nucleus increases attraction so IE increases
Shielding-more electrons in filled inner shells repel electrons in the outer shell more strongly-less attraction IE decreases
