Clarification:

In order to look for similar elements, you need a proton number, but you need to remember that there will always be two on the first bracket) 2 on the second bracket there will be eight) 8, and on the last, that is, on the third bracket, there will be a remainder. To further calculate these elements, you need to know that s are puddle and puddle-earth elements, that is, (red), p is (yellow) b is (blue), and f is generally the bottom two rows (green), but none of them does not use.
