Let’s start by finding the location on the periodic table for the atoms for substances that conduct when dissolved. What do you notice about where the atoms are?

Explanation:

This question appear incomplete. However, chemical substances that conduct electricity when dissolved in water are elctrovalent/ionic compounds. These compounds are usually made up of elements in group 1 and group 7 (for example NaCl, NaI and LiF) but could also be made up of group 2, group 3 and group 6 [for example Mg(OH)₂ and Al(OH)₃]. Thus, they can be loosely said to be found in those groups in the S and P blocks of the periodic table.

NOTE:

Sodium (Na) is found in group 1 (S-block)

Lithium (Li) is found in group 1 (S-block)

Chlorine (Cl) is found in group 7 (P-block)

Iodine (I) is found in group 7 (P-block)

Flourine (F) is found in group 7 (P-block)

Magnesium (Mg) is found in group 2 (S-block)

Aluminium (Al) is found in group 3 (S-block)

Oxygen (O) is found in group 6 (P-block)

Hydrogen (H) is found in group 1 (S-block)
