Electrons And Light

Question 1

What’s energy level

Answer 1

Indicates energy content of electron, indicated by numbers, lower energy level equals lower energy electron has

Question 2

What’s sublevel

Answer 2

Describes the shape of the path the electron follows around a nucleus, represented by letters

Question 3

What’s atomic orbital

Answer 3

Describes electrons position within energy level

Question 4

What’s the s sublevel(how is it shaped how many orbitals)

Answer 4

Sphere shaped, 1 orbital

Question 5

P sublevel

Answer 5

Dumbbell shaped (figure 8 pathway)
Contains 3 orbitals (boxes where electrons are, think like that)

Question 6

D sublevel

Answer 6

Dumbbell shaped (figure 8)
Contains 5 orbitals

Question 7

F sublevel

Answer 7

Dumbbell shaped (figure 8)
Contains 7 orbitals

Question 8

Aufbau principle

Answer 8

Electrons enter orbitals of lowest energy first

Question 9

Pauli exclusion principle

Answer 9

An atomic orbital may contain a maximum of two electrons with opposite spins

Question 10

Hunds rule

Answer 10

When electrons occupy orbitals of equal energy, one electron enters each orbital until all orbitals contain one electron with parallel spins

Question 13

Ground state atom

Answer 13

All electrons are in lowest energy level

Question 14

Excited state atom

Answer 14

Atom in which electrons have absorbed energy and are located at higher energy rates (ex light energy, heat, chemical reactions)

Question 15

Quantum numbers

Answer 15

Numbers that describe locations and spin of an electron

Based on solutions off the Schrodinger Equation

Question 16

What are the four quantum numbers and how do you write quantum numbers

Answer 16

1. Principal quantum number (n) energy level, 1,2,3,4,5,6,7
2. Angular momentum quantum number (l) designates the sublevel, values: s-0,p-1,d-2,f-3
3. Magnetic quantum number (ml) designates orbital within sublevel
   S orbital-0, p- -1,0,1 d- -2,-1,0,1,2 f- -3,-2,-1,0, 1,2,3
4. Spin quantum orbital (ms) spin of electron, +1/2, or -1/2

Question 17

What are diamagnetic elements

Answer 17

All electrons have paired spins
All sub levels filled
Are not strongly affected by magnetic fields

Question 18

Paramagnetic elements

Answer 18

Don’t have all electrons with paired spins
Don’t have all sublevel filled
Are strongly affected by magnetic fields
