Atomic radius Flashcards
1
Q
Atomic radius
A
Half of the distance between two nuclei of the same element that are joined together by a single covalent bond
2
Q
Does the Atomic radius increase of decrease going down and why?
A
Increase- new energy level , increase in screening effect
3
Q
Does the Atomic radius increase of decrease going across and why?
A
Decrease- no increase in screening effect , increase on effective nuclear charge (number of protons increase meaning greater attraction on outer electrons)
