Ions
What is an ion?
A non-neutral atom which has a different number of electrons.
What orbital has a spherical shape?
s, p, d, or f?
s
What does the Aufbau Principle state?
Electrons fill orbitals from lowest to highest energy
How is the periodic table arranged?
In order of atomic number (number of protons)
What is the positively charged subatomic particle?
Proton
Cation
s, p, d, or f?
p
Why is it important to use Hund's rule?
(Hint: The rule that states you must put all up arrows before the down arrows)
To get the correct number of unpaired vs paired electrons.
Which direction does Electronegativity increase?
Up or Down
and
Left or Right
Up and Right
What does the atomic number tell you?
Number of protons
What do you call a negatively charged ion?
Anion
How many electrons does the s and the p orbital hold?
s=2
p=6
Give me the electron configuration for Nitrogen.
Teacher Approval
Which direction does Atomic Radius increase?
Up or Down
and
Left or Right
What is the relative mass of an electron?
~0 amu
When the overall charge is positive, do you add or subtract electrons?
Subtract. A positive charge means less electrons than protons!
How many electrons does the d and the f orbital hold?
d=10
f=14
Give me the electron configuration for Iron.
Teacher Approval.
Rank these in order of increasing Electronegativity:
P, Cl, Ar
Ar < P < Cl
Where are the three subatomic particles located relative to the nucleus?
Protons and Neutrons = Inside the Nucleus
Electrons = Outside the Nucleus
The overall charge of a Silicon ion is -2. How many electrons does this ion have?
18 electrons
Define what the quantum model describes about electrons? Where are they and how do they move?
They can be found in the different atomic orbital shapes, they do not have a fixed path.
Give me the orbital diagram for Phosphorus.
Teacher approval
Rank these in order of INCREASING atomic radius:
Al, P, S
S < P < Al
How many neutrons are in an atom of Neon-20.
(Neon's atomic number is 10)
10 neutrons
Mass - Atomic Number = Number of Neutrons
20 - 10 = 10
