A substance has an extended structure composed of two different elements. The elements are a metal and a nonmetal. Which property would this substance most likely have?

Multiple choice question.

A) can be hammered into sheets
B) has a high melting point
C) does not dissolve in water
D) is a gas at room temperature



Answer :

A substance has an extended structure composed of two different elements. The elements are a metal and a non-metal. The property would this substance most likely have is (B) has  a high melting point.

When a metal and a non - metal combine it will  form ionic compound. while when nonmetals combine with other nonmetal it will form covalent compound.

An ionic compounds have high melting point because an electrostatic force between particles is very high and difficult to break. so due to high electrostatic attraction between ions.

Thus, A substance has an extended structure composed of two different elements. The elements are a metal and a non-metal. The property would this substance most likely have is (B) has  a high melting point.
