1 Electrons Protons and Neutrons
By lord Vamsi and annoying Jesse

2

3 Atoms as we know of consists of proton, neutron and electrons
Proton are generally positive charge Electrons are negative Neutrons have no charge This model is a 3D structure model of an atom Reference to :  chemistry/rutherford-model-of-the-atom.html Additional points to make – in reality think of them as a 3D shape

5 Table

6 Protons (they are positive)
Elements are determined by proton numbers Periods of the periodic table Positive No. Of protons = no. Of electrons

7 Neutrons (unemotioned)
No. Of neutron = no. Of relative mass – no. Of protons Isotopes*

8 Electrons (they are special)
Their mass are so small that their mass is considered 0 (2,8,8,2) order true only from hydrogen to calcium Electronic configuration is determined by s,p,d,f shells D shells after calcium actually determines the electron configeration For more information of s,p,d,f shells Erica's and Engila's group will explain

9 Isotopes each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei E.g. Carbon-12, Carbon-14, Hydrogen etc

10 Ever wonder?

11 Why does proton and neutron are in the centre of necleus and electrons are orbiting around like a planet and a moon?

13 Well The nucleus of an atom is held together by the strong nuclear force that binds together protons and neutrons. Although the strong nuclear force is the strongest of the four fundamental forces, it acts only over very short - typically nuclear - distances. It binds together the protons and neutrons in the nucleus. It also holds together the quarks that make up those protons and neutrons and the other hadrons. Reference : Confused? 

14 How does strong force works
Mesons – exchanging particles Pressure – Great High speed Easier to add neutrons than protons Protons and neutrons are made up of smaller subatomic particles. When protons or neutrons get close enough to each other, they exchange particles (this is called mesons), binding them together. Once they are bound, it takes considerable energy to break them apart. To add protons or neutrons, the nucleons either have to be moving at high speed or they need to be forced together under great pressure. Although the strong force overcomes electrostatic repulsion, protons do repel each other. For this reason, it's usually easier to add neutrons to an atom than to add protons.

15 How is electron not attracted to protons and neutrons in nucleus?
We can't explain that in this stage it is quantium theory Scienctist fired alpha particle at a golden sheets and some alpha particles deflected and some when through and the detector detects it so it is definitely not in the nucleus Chemistry IB books

16 END Thank you so much (finally someone actually listens to me)
