Question 4

How do you deduce the electronic configuration rom the periodic table

Answer 4

Number of electrons in the outermost shell is the group number. Total number of electrons in the shell is the atomic number. Number of shells is the period number.
E.g oxygen electronic configuration is 2,6

Question 5

Why are noble gases un reactive

Answer 5

Their outer electron shells are completely full

Question 6

Why do groups in periodic tables react similarly

Answer 6

They have the same number of electrons on their outer shell
