When comparing the two elements ga and as , the element with the higher first ionization energy is as based on periodic trends alone?

As has more ionization energy.

Explanation:

Ga is the element of forth period and 13 group.

The electronic configuration is -  

As is the element of forth period and 15 group.

The electronic configuration is -  

Since, As is half filled in 4p orbital it is more stable. Hence, more energy is required to knock out the valence electron.

Hence, As has more ionization energy.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
