Entry 5

Hey!

Today i learned about the Atomic Structure! An Element is made up by Molecules. An Element consists of Atoms and Sub-atomic particles this makes up the Periodic table. The sub-atomic particles are the protons, neutrons and electrons. Everyone/ Everything have sub-atomic particles just that they have different number. 

This is a diagram of an atom. Protons and Neutron make up nucleons. The second diagram shows the different charges of protons, neutrons and electrons. Proton is represented by the symbole (h). So its charge is h+. Electrons is represented by the symbol (e), so its charge is (-e). Neutron has no charge.

Electrons move about freely and randomly. Shells and orbitals put in place to assist studying. 

amu=atomic unit mass/relative mass. Electrons do not deviate due to (-e), proton is (+h). Negative and positive charge attract each other. 

This diagram also shows the respective relative mass of proton, neutron and electron. 

Atoms are electrically neutral as they have equal number of (+h) proton and )-e) electron. Hence, proton = electron. Atoms of different elements have different proton number. Each proton number is unique to a specific atom only. 

Nucleon number (proton+neutron)= mass number. 

E.g 12C (12=nucleon, 6=proton.) Since proton+neutron=nucleon. Nucleon-proton = neutron. So the neutron number is 12-6=6. Since the atomic mass of both proton and neutron is 1 respectively, its totally relative mass will be....

6p=1*6=6

6n=1*6=6

Total relative mass=6+6=12

Alright! This will be all for today! Thank you :)
