Use the periodic table to write electron configurations for each element.(a) Sr(b) Y(c)

Solution 67P

Step 1:

Here, we have to use the periodic table to write electron configurations for each element :

Let’s look at the periodic table below :

Periodic table has 4 blocks, which is ‘s’, ‘p’, ‘d’, and ‘f’. Each group in the periodic table has respective block’s name and the number of electrons it can hold. Based on this we write the electronic configuration.
