Test #2 prep

Question 1

Quantum Mechanical

Answer 1

Model of an atom to Explain the way in which electrons exist and behave.

Question 2

Orbitals

Answer 2

Volume in space with high probability of finding the electron

Question 3

Quantum Numbers

Answer 3

To describe the orbitals each electron is described by a unique set of quantum numbers.

Question 4

Angular Quantum Number (L)

(principle 2)

Answer 4

Sublevel (subshell)

Specific type of orbital

Value given by L is given by numvers that go from

• 0 to N-1

Each possible value of L represents a sublevel

(a specific type of orbital)

Value Of L Type of orbital

0 S

1 P

2 D

3 F

Question 5

Quantum Number (N)

(Principle 1)

Answer 5

Represents the Energy level (or shell)

Values 1-7

It is given by the peroids on the perodic table

Question 6

Magnetic Number (ML)

(Principle 3)

Answer 6

How many orbital of each type

Ex. if there are three possible values of Ml. There are 3 orbitals of that specific type of orbital.

• Value of ML
• L to +L

Ex, if L=3

-3, -2, -1, 0, 1, 2, 3

7 possible values of ML (7 orbitals)

Question 7

Spin Quantum Numbers (MS)

(Principle 4)

Answer 7

electron configuration

+1/2 up or -1/2 down

Question 8

Ionic Bonds

(compound)

Answer 8

transfer of electrons

M X

M= metal always +

X= Negative

example, NaCl

Question 9

Covalent or Molecular Bond

(compound)

Answer 9

Sharing of electrons

Example, CO₂

NON METALS!!!

Question 23

IsoElectronic

Answer 23

When an ion and an Atom have the same number of e-‘s

(so same e- configuration)

trying to be like a noble gas

Example, Ca⁺² Iso electronic trying to be like Ar or Argon

Question 24

Pauli Exclusion principle

Answer 24

no two electrons in an atom have the same set of quantum numbers

n, l, ml, ms< in regards to spin

Question 25

Aufbau Principle

Answer 25

orbitals of the lowest energy are filled first in gerneral

exceptions transition metals

Question 26

hunds rule

Answer 26

multiple orbitals of the same energy

fill one electron in each orbital before pairing electrons
