An atom of element x has one more shell of electrons than an atom of beryllium, but it has one less valence electron than beryllium. which is element x? a. sodium b. boron c. magnesium d. lithium

Element X is Na, sodium.

Be is in Row 2, Group 2 and has two valence electrons.

The element with one more shell of valence electrons is Mg, magnesium in Row 3, Group 2.

If the element has one less electron than Be, it must be in Row 3, Group 1: Na, sodium.

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.
