Which type of bonding is present in a sample of an element that is malleable?
(1) ionic
(2) metallic
(3) nonpolar covalent
(4) polar covalent

Malleable means that something can be hammered into sheets, which is a property of metals.
Having that in mind, the type of bonding that is present in a sample of an element that is malleable is (2) metallic.

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
