1 What do you know about atoms? On your paper, draw and label the parts of the atom Protons Electrons Neutrons Nucleus Electron Cloud
2 Here is the model of an ATOM! Check your drawing and correct
3 Atoms Everything is made of atoms the smallest part of something that is still that substance Atoms are made of a tiny, heavy nucleus surrounded by a big, light electron cloud
4 The Atom Part Location Charge Mass Proton Electron Neutron
5 Parts of the Atom (subatomic particles) ++++ Protons are positive and are found in the nucleus. (p + )
6 Parts of the Atom (subatomic particles) 0000 Neutrons (n 0 ) don t have charge at all (neutral) and are in the nucleus.
7 Parts of the Atom (subatomic particles) ---- Electrons (e - ) are negative and are in the electron cloud.
8 What does this figure tell you about the mass of the different subatomic particles? n 0 p + e - p electrons p +
9 Mass of the atom The mass of the proton and neutron are about the same. We call the mass of one proton 1 amu The mass of the electron is 1/2000 th of a proton. It is so small that we usually ignore the mass when talking about the atom.
10 The Atom Part Location Charge Mass Proton Nucleus Positive + Heavy (1 amu) Neutron Nucleus Neutral 0 Heavy Electron Electron cloud Negative (1 amu) Very light
11 Who am I? I have a negative charge I have a positive charge I have mass but no charge I am found in the nucleus I have very little mass I am where electrons are found I am where almost all the mass of an atom is found
12 Periodic Table of the Elements Each box on the periodic table gives information on an element. There are about 115 elements in the world.
13 ELEMENT 14 Si Silicon Atomic Number Element Symbol Element Name Atomic Mass
14 Atomic Number Tells us the number of Protons in the an element. Find Carbon, C on your periodic table. How many protons does Carbon have?
15 How do we know how many electrons there are? Atoms have the same number of protons and electrons. (Same + as -) So, if carbon has 6 protons, how many electrons does it have? How many electrons are in Ca?
16 Remember APES Atomic number Protons Electrons Same
17 We now have to calculate how many neutrons there are. Atomic mass = # protons + # neutrons Number of Neutrons = Atomic Mass Atomic Number 9 F flourine Atomic Number Atomic Mass
18 First we need to round off the atomic mass to a whole number Look at the first number after the decimal 0-5 just ignore 5 or more add one more Round off = 19
19 Figure out how many of each 11 Na Sodium Atomic Number = Atomic Mass= Round off= P = E= N=
20 Figure out how many of each 11 Na Sodium Atomic Number =11 Atomic Mass=22.99 Round off to 23 P = 11 E= 11 N= = 12
21 Now work the problems on your worksheet. Be ready to review answers with your class in 10 minutes.

23 Warm up The picture shows a model of the element A fluorine B helium C beryllium D oxygen
24 How to Bohr 2 p + 2 n 0 A Bohr model draws electrons on rings (orbits or energy levels) around the nucleus. It is not really how atoms look, but it is a model that helps us learn about an atom s properties..
25 Bohr Diagrams 1) Draw a nucleus 6 p + 6 n 0 2) Use the periodic table to find out how many protons and neutrons the element has.
26 Bohr Diagrams 6 p + 6 n 0 3) Find out how many electrons you need. (Carbon has 6 electrons.) 4) The first shell can only hold 2 electrons.
27 Bohr Diagrams 1) Since you have 2 electrons already drawn, you need to add 4 more. 6 p + 6 n 0 2) These go in the 2 nd shell. 3) Add one at a time - starting on the right side and going counter clock-wise.
28 Bohr Diagrams 6 p + 6 n 0 1) Check your work. 2) You should have 6 total electrons for Carbon. 3) Only two electrons can fit in the 1 st shell. 4) The 2 nd shell can hold up to 8 electrons. 5) The 3 rd shell can hold 18, but the elements you will do will only use 8 electrons.
29 Bohr Diagrams 6 p + 6 n 0 Try the following elements on your own: a) H b) He c) O d) Al e) Ne f) K
30 Bohr Diagrams 1 p + 1 n 0 Try the following elements on your own: a) H 1 electron b) He c) O d) Al e) Ne f) K
31 Bohr Diagrams 2 p + 2 n 0 Try the following elements on your own: a) H b) He - 2 electrons c) O d) Al e) Ne f) K
32 Bohr Diagrams 8 p + 8 n 0 Try the following elements on your own: a) H b) He c) O - 8 electrons d) Al e) Ne f) K
33 Bohr Diagrams 13 p + 14 n 0 Try the following elements on your own: a) H b) He c) O d) Al - 13 electrons e) Ne f) K
34 Bohr Diagrams 10 p + 10 n 0 Try the following elements on your own: a) H b) He c) O d) Al e) Ne - 10 electrons f) K
