Problem 2 Analyze statements i, il, and ili as true or false. Explain why each is true or false. Circle the correct answer A through E Which of the following statement(s) is/are correct about trends in atomic i. Ba is larger than Sr because the last electron added has a higher value of and ionic radius the angular momentum quantum number ( This statemat is tne ii. Within a period, atomic size decreases as you go across the periodic table from left to right (alkali metals to noble gases) because the effective nuclear charge increases.

Explanation / Answer

Problem 2

Solution:-

D. i and ii

i. This is true Ba is larger than Sr is true because both are belongs same family and within a family or vertical column of the periodic table, the atomic radius increases regularly with the atomic number.

ii. This is true, the atomic size generally decreases across a period. It is because within the period the outer electrons are in the same valence shell and the effective nuclear charge increases resulting in the increased attraction of electrons to the nucleous. within a family or vertical column of the periodic table, the atomic radius increases regularly with the atomic number.

iii. This is false A cation is smaller than that of the parent atom bacause it has fewer electrons while its nuclear charge remains the same.
