Question
1) Each of the statements below attempts to explain why some periodic property varies predictably among elements in the periodic table. Determine if each statement is true or false.
A) True FaleWithin a family, elements with lower atomic numbers pull more strongly on electrons in a bond, because the atoms have higher effective nuclear charge.
B) True False Within a period, elements with higher atomic numbers require more energy to remove an electron from the atom, because the atoms have higher effective nuclear charge.
C) True False Within a family, elements with higher atomic numbers require less energy to remove an electron from the atom because the valance electrons are in lower principal energy levels.
D) True False Within a period, elements with higher atomic numbers have higher ionization energy because the valance electrons are in higher principal energy levels.
E) True False Within a family, elements with higher atomic numbers have higher ionization energy because the atoms have higher effective nuclear charge.
F) True False Within a period, elements with higher atomic numbers have atoms of smaller radius because the atoms have lower effective nuclear charge.

Ans 1
A) False
In the period , size decreases due to more pull from nucleus , due to increase in the net effective charge.
B) True
In the period ionization energy increases from left to right.
C) False
As the size increases , the lectrons occupy higher energy levels.
D) false
The electrons are in the same energy level in the period , only the net effective charge increases.
E) False
The ionisation energy goes on decreasing from top to bottom in the family.
F) false
Though the size becomes smaller , but it is due to higher effective charge
