Electron Configuration
Flashcards do conjunto (20)
- 1Electron configurationhow electrons are arranged into the atomic orbitals in an atom.
- 2Pauli Exclusion PrincipleThere cannot be two electrons in the same atom with the same set of four quantum numbers. Hence, AN ATOMIC ORBITAL CAN HOLD A MAXIMUM OF TWO ELECTRONS AND THEY MUST HAVE OPPOSITE SPINS.
- 3Hund’s ruleAn electron will be arranged separately into an empty orbital with the same energy before pairing.
- 4paramagnetic substancesubstance that is weakly attracted by a magnetic field; it usually has unpaired electrons in atoms.
- 5diamagnetic substancesubstance that is not attracted by a magnetic field generally because it has only paired electrons.
- 6Show electron configuration for Phosphorus (P) atom.
- 7Show condensed electron configuration of bromine (Br) atom.
- 8Show orbital diagram of valence electron of sulphur (S) atom.
- 9—period 3 group 3A
- 10—Gallium (Ga)
- 11—
- 12Define: First ionization energyThe amount of energy that must be added to remove an electron from a neutral atom in gaseous state to give a cation.
- 13Define: Electron affinityThe amount of energy released when an electron adds to a neutral atom to give an anion.
- 14Elements in group 7A are called_________.Halogen
- 15Alkali metals are in which group in periodic table?Group 1A
- 16Compare first ionization energy of metals and non metals.Metals has low first ionization energy than non metals.
- 17What is Zeff ?Effective nuclear charge (Zeff) is the net nuclear charge actually experienced by an electron.
- 18Give examples of alkaline earth metals.Group 2A elements : Be Mg Ca Sr Ba Ra
- 19Show orbital diagram of chromium (Cr) atom.
- 20Show electron configuration of copper (Cu) atom.
