Interpretation:
The four different molecular formulas were given in the statement and which is one incorrect need to identify.
Concept Introduction:
Atomic radius: The concept explain chemical element is a measured of the size of its atoms, in other words to measure the distance from the center of the nucleus to the boundary of the surrounding cloud of number of electrons.
Increase and decrease electronegativity: The less vacancy electrons an atoms has the least it will gain of electrons. Moreover the
