4:metallic
Answers
Answer:
metallic i think its correct answer..
Answer:
METALLIC
Explanation:
The transition metals and inner transition metals form a large variety of compounds with hydrogen, ranging from stoichiometric compounds to extremely complicated nonstoichiometric systems. (Stoichiometric compounds have a definite composition, whereas nonstoichiometric compounds have a variable composition.) Metallic (formerly termed interstitial) alloylike hydrides possess some of the characteristics of metals, such as lustre and strong electrical conductivity. They tend, however, to have variable physical properties, with some being more brittle and others being harder than the metals from which they are made. Such compounds are regarded as intermediate in nature between salts and alloys. Metallic hydrides essentially consist of protons (positive hydrogen ions, H+) and metal atoms in an electron sea. The lustre and electrical conductivity are attributed to the relative freedom of electron movement in the hydride.
