Which property do metalloids share with nonmetals? both are gases at room temperature. both can react to form acidic compounds. both are very poor electrical conductors. both can be pounded into thin sheets?

Metalloids and nonmetals are chemical element that can react to form acidic compound. Most nonmetal oxides react with water to directly give a proton and conjugate base of the oxyacid to form acids and resultant acidic solutions. Meanwhile, metalloids have weakly acidic property, which are usually found naturally in combined states.

they can react from acidic compounds. hope this helps!

the atomic mass is the bottom number on the element.
