Hi there.
00:03
In this question, we want to write the condensed electron configuration for tellurium, which is te.
00:10
Looking at the periodic table, we see its atomic number is 52, and it's found in period 5 and group 6a.
00:32
Okay, so if we are writing its configuration, its atomic number is 52, so that means it has 52 electrons.
00:41
Because it has 52 protons, according to that 52, and since it's neutral, it would also have those 52 electrons.
00:53
All right, so since it's in period 5 to write this configuration, we need to look for the noble gas in period 4.
01:00
That represents the core electrons of tellurium, and that is krypton.
01:07
So that represents the first 36 electrons.
01:10
Now we need to go across that fifth period writing the rest of the configuration.
01:16
So first we come to the s block.
01:19
So we need to fill in 5s2.
01:22
Then we come to the d block...
