Question

chemistry h - koenig - 02 - 06 (lms) investigation test: the periodic table (lms graded) 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 Period 3, the element with the largest atomic radius is Na.

Step2: Recall ion - size comparison

Cations are smaller than their parent atoms. Among Al, Mg, and their parent atoms, the ions of these elements are smaller in size than their parent atoms.

Step3: Recall ionization - energy trend

Ionization energy generally increases across a period and decreases down a group. In Group 6A, O has the highest ionization energy among the common elements in this group shown (O, S, Se).

Answer:

1. Na
2. Al, Mg ions
3. O
