- 1ATOMIC STRUCTURE
- 2Electrons StructureThe electronic structure of an atom is written using numbers to represent the electrons in each energy level.
- 3Mass spectrometersimplest application is to determine relative atomic mass of different isotopes of an element.
At (tl) = %*Ar +%*Ar /100
(79*24)+(10*25)+(11*26)|100
=24.32 - 4Isotopesare atoms of same element having the same atomic number but different mass number.
Atomic number - number of protons
Mass number -number of protons and neutrons.
- 5Periodic Trendselectronegativity-F IS Highest
Atomic Radius-He is smallest
lionization energy-He is largest
