reason
Elements
Electronicconfiguration
Na
2, 8, 1
S
2, 8, 6
Al

K
2, 8, 8, 1​

Answer 1

Answer:

The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.

Answer 2

Answer: K is smaller than NA is smaller than MG is smaller than S

Because electronegative increases from left to right in the modern periodic table whereas decreases from top to bottom
