Question

arrange the following elements in order of decreasing atomic size. rank values from biggest to smallest atomic size. to rank items as equivalent, overlap them. s si rb ge f ca largest atomic size smallest atomic size submit request answer

Explanation:

Step1: Recall atomic size trends

Atomic size increases down a group, decreases across a period.

Step2: Locate elements on periodic table

Rb (Group 1, Period 5), Ca (Group 2, Period 4), Ge (Group 14, Period 4), Si (Group 14, Period 3), S (Group 16, Period 3), F (Group 17, Period 2).

Step3: Rank by size rules

Down groups: Rb > K > Ca; Ge > Si; S > O > F. Across periods: Ca > Ge; Si > S.

Answer:

Largest atomic size: Rb
Ca
Ge
Si
S
Smallest atomic size: F
