Final answer:
The abbreviation for tin's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p2, also written as [Kr] 5s2 4d10 5p2.
Step-by-step explanation:
The correct abbreviation for tin's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p2. This is because tin (Sn) has an atomic number of 50, meaning it has 50 electrons in its neutral state. The configuration shows that the 5p orbital has two electrons, as tin is located in the second column of the p block in the periodic table. Using the noble gas shorthand, this configuration can also be written as [Kr] 5s2 4d10 5p2.
