Question

use the figure to enter the correct symbol for the elements. an element may be used more than once or not at all. from the group 6a elements shown in the diagram, the element with the largest atomic radius is. in period 3, the element with the largest atomic radius is. the three atoms would form ions which are smaller in size than their parent atoms are al, mg, and. in period 3 has the highest ionization energy, while in group 6a has the highest ionization energy. question 10 of 15

Explanation:

Step1: Recall atomic - radius trend

Atomic radius increases down a group and decreases across a period. In Group 6A, the element with the largest atomic radius in Period 3 is S (sulfur).

Step2: Recall ion - size comparison

When atoms form ions, cations (formed by metal atoms like Al and Mg) are smaller than their parent atoms. Al and Mg are metals in Period 3. Al³⁺ and Mg²⁺ are smaller in size than Al and Mg respectively.

Step3: Recall ionization - energy trend

Ionization energy generally increases across a period. In Group 6A, the element with the highest ionization energy is O (oxygen) due to its relatively small atomic size and high effective nuclear charge.

Answer:

1. S
2. Al³⁺, Mg²⁺
3. O
