4.2 Atomic Attraction Flashcards
coulumbic attraction equation
F=K(q1*q2)/r^2
F equals
electrical force
k equals
coulumb’s constant
q1 equals
charge of 1st particle
q2 equals
charge of second particle
r equals
distance between particles
charge and force are
directly related
force is inversely related to
the distance squared
distance from nucleus
the further away from the nucleus an electron is, the less force of attraction
amount of protons in the nucleus
the more protons there are in the nucleus, the stronger the attraction
amount of electrons between nucleus and valence shell
similarly charged particles repel each other and ‘shield’ valence electrons.
as you go across the periodic table towards the right
the number of protons in the nucleus increases, causing the attraction to be stronger
as you go down the periodic table
the distance from the valence electrons to the nucleus increases, which decreases the attraction
across to the right
increase of attraction
down
decrease of attraction
