Cards in this deck (7)
- 1Increase in shell number n effect on S-orbitalGreater the S orbital radius
- 2Increase in shell number n effect on p-orbitalFurther p orbital is from nucleus
- 3What sub-shells are present in shell 3?3s,3p,3d
- 4Within a sub-shell, all orbitals have the same ___Energy
- 5Explain shape of CH44 pairs of bonded electrons around central carbon atom
Repel each other, arrange themselves as fair in space to minimise repulsion
Form a tetrahedral arrangement
109.5' - 6Explain shape of NH33 bonded pairs of electrons
repel
lone pair of electrons, lone pairs repel more strongly than bonded pairs
reduces bond angle between bonded electrons by 2.5'
