People and Electrons
Bohr's model: name and explain
Planetary model, multiple levels
Principle quantum number: Energy level
What is the letter symbol?
n
Where do you find the metals?
On the left, most of the periodic table
What is ionization energy?
The energy needed to remove and electron from an atom
Where are the largest atoms (atomic radius)
Bottom left
When atoms absorb energy, electrons do what?
They jump to a higher energy level.
Sublevel quantum number. What is its letter symbol?
l
Which group of the periodic table is very unreactive?
Noble Gases, group 18
What is electronegativity?
The strength of the attraction of a nucleus to electrons of another atom.
Will ionization energy be higher for group 1 or 2?
2
Whose rule: Half fill electron orbitals in a sublevel before double filling them.
Hund
What are the letters for the different sublevels? (0, 1, 2, 3)
What are the names of the (2) groups that are found in the s block?
Alkali Metals, Alkaline Earth Metals
What could cause atomic radius to increase?
Increase number of energy levels.
Have very few electrons in the outer energy level
Which one has the higher electronegativity? Sulfur or aluminum
Sulfur
Who: explained the energy levels and sublevels in terms of which ones will be filled first in any given atom.
Aufbau
Which sublevels can go in energy level 2? What is the maximum number of electrons in energy level 2?
s, p. 8
Where should the f block fit into the rest of the periodic table?
Between the s and d block on periods 6 and 7.
Right where Lanthanum and Actinium are found
Is it harder to remove the first or second electron from an atom?
First ionization energy is typically lower than the second. It is easier to remove the first electron. The nucleus will hold the remaining electrons stronger after the first one is removed.
Which has a greater electronegativity, chlorine or argon?
Argon has no electronegativity. It is a noble gas.
So it would be chlorine
Whose principle: Electrons cannot have the same energy level, sublevel, orbital, and spin. (electrons in the same orbital need to have different spins)
Pauli - Pauli's exclusion principle
How many orbitals are in the d sublevel? How many electrons fit in a d sublevel?
5, 10
What types of atoms are found in the p-block. (There are multiple groups and types)
transition metals, metalloids, non-metals, halogens, noble gases
Why are the patterns the same for ionization energy and electronegativity?
If it is easy to remove an electron (low ionization energy) then the atom has a weaker attraction to its own electrons, and likewise, electrons of other atoms (low electronegativity)
Compare the atomic radius, electronegativity, and ionization energies of: Calcium and Potassium
Potassium has a larger radius, calcium has a higher electronegativity and ionization energy
