List the following in order of smallest to largest atomic radius: si, fe, ci, k, ca ! : )

Cl < Si < Fe < Ca <K

The atomic radius decreases from left to right across a period and increases from top to bottom in a group.

Thus, the largest atoms are at the lower left and the smallest are at the upper right.

Locate the atoms in the Periodic Table (see the attached image).

In decreasing order of size, K > Ca > Fe > Si > Cl.

The order from smallest to largest is Cl < Si < Fe < Ca <K.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
