Atomic Structure

- 1Atomic StructureIsotopes
- Isoelectronic =atoms/molecules/ions have same no. of electrons
- Isotonic = same no. of Neutrons
-Isotopic = same no. of Protons - 2Behaviour of particles in an Electric Field - Positively charged protons deflect towards negatively charged plates - Negatively charged electrons deflect towards positively charged plates -Neutrons not deflected/unaffected * Electrons deflect by larger extent as it is lighterDeflection angle of particles depend on mass and charge
Deflection angle= k(Charge/mass) - 3Principle Quantum Shell(PQS)=electron shell For every PQS, there is a principle quantum number,n. As n increases, size of orbital increases, distance of the orbital from the nucleus increases, the higher the energy of the orbitalAufbau Principle
Filling order of electronic confirguration is:
1s,2s,2p,3s,3p,4s,4d,4p,5s,4d
Writing order of electronic configuration is:
1s,2s,2p,3s,3p,3d,4s - 4Types of Notation 1. 'Electron-in-Box' Diagram 2. spdf notation 3. Noble Gas Core configuration *Dont give answer in the Noble gas core format if the Question didnt ask you toKey Atomic properties
- 1st I.E is the energy required to remove 1 mole of electrons from 1mole of gaseous atoms to form 1 mole of gaseous singly-charged cations
- Electronegativity is the ability of an atom to attract electrons to itself within a covalent bond
- Atomic radius - 5—
