2.2 Flashcards
How is the force when the charges are the same?
They move away from each other.
How is the force when the charges are different?
They move towards each other.
If you double the amount of charge of one particle, how does the amount of force change?
They repel each other the amount they are doubled.
How does the amount of charge affect the strength of coulomb strength?
The force goes down.
If you double the distance between the particles, how does the force change?
The farther away the charges are, the lesser the force, if close, the more the force.
Which has a larger effect on the amount of force, the amount of charge, or the distance between particles?
The charge has more attraction.
How can you get the strongest attraction between the two atoms?
Increase the magnitude all the way with two atoms of opposite charge and move the atoms as close together as possible.
What is the equation for coulombic attraction?
F = k * q1 * q2 / d2
How is force related to charge?
directly related to the charge of each object
How is force related to distance?
The greater the force that is applied on an object the further distance that object will travel.
How is the attraction for valence e- affected?
distance from the nucleus, amount of protons in the nucleus, amount of electrons between the nucleus and valence shell
How does the nucleus change as you go across a row on the periodic table?
the number of protons increases and therefore the nuclear charge increases
How does going across a row on the period table, affect attraction for valence e-?
They experience a smaller force of attraction
How does atomic structure change as you go down?
the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius
How does it affect attraction for valence e-, when you go down?
the attraction between the electron and the nucleus decreases
