Charged Conversations
Force and magnitude of charge have what kind of relationship?
Directly proportional
If the distance between 2 charged objects increases, the force will _______________.
Decrease
Ionization energy and electronegativity trend in the same direction on the periodic table. Describe this trend.
From left to right, bottom to top
What is the equation for Coulomb's Law?
F = q1q2/d^2
Define effective nuclear charge and the equation to solve for it.
Effective nuclear charge is the total positive force of the nucleus, accounting for the repulsive effects of the shielding electrons.
Zeff = Z - S
How do we determine the number of energy levels that an element occupies?
Count down the periods
In what direction does atomic radius increase?
When considering elements in the same period, what variable in Coulomb's Law is being affected?
DOUBLE JEOPARDY: When looking at elements in the same group, what variable in CL is being affected?
If charge 1 is doubled and charge 2 is halved, by what factor will force be influenced
None! 2 and 1/2 cancel out
Distance is quadrupled. By what factor will force be impacted?
Force x 1/4
Describe the ways that distance and charge influence the trend for ionization energy.
Ionization energy increases from left to right because the effective nuclear charge is increasing. IE increases from bottom to top because with fewer energy levels there is a lower distance between the nucleus and the electron, so the force is greater.
What mathematical function is occurring between the charges in Coulomb's Law?
Multiplication
