Isotopes

- Atoms of same element

- Same atomic number

- Therefore they share the smaechemical properties

- Due to same electonicconfiguration of both isotopes

- Different mass numbers(number of neutrons different)

- Different physical properties(Density, melting point and boilingpoint)

Electronic Configuration

- Electrons arranged around thenucles in the shells of an atom

- Shells number 1,2,3 and so on

- Each shell can occupy acertain number of electrons

- Finding electron configuration

- Find the proton number of the atom

- Find out the numbers of electrons fromthere. (number of protons = number ofelectrons)

- Arrange the electrons in shells. Electronsoccupy the shell closest to the nucleusfirst

- Electrons only start occupying a newshell when the previous one has beenoccupied

- Valence Electrons

- Electrons found in theoutermost occupied shell of anatom

- Outermost shell refers to theshell which is furthest from thenucleus

- Nature of elements can bedetermined by the number ofvalence elctrons

- 1-2 are metallic. Theexception being aluminiumwith 3

- 4-8 are generally non-metallicelements

Gains or loses Electrons

- Ions

- Gain electrons

- Usually non-metals

- Anions

- Ions are negatively charged

- Lose electron

- Cations

- Usually a metal

- Ions are positively charged

Combines Chemically

- Molecules

- Molecules of compounds

- Consists of atoms of differentelements

- Examples

- Hydrochloric Acid

- Methane

- Ammonia

- Carbon dioxide

- Water

- Molecules of elements

- Consists of atoms of thesame element

- Examples

- Nitrogen

- Hydrogen

- Oxygen

- Chlorine

- Phosphorus

One Atom Consist of..

- Electron

- Hold a negative charge

- mass of 1/1836

- 1/2000 the mass of a proton

- Number of electron andneutron = mass number

- Neutron

- No charge

- mass of 1

- Proton

- Holds a positive charge

- mass of 1

- Number of protons = atomic number
