The bond formed by the attraction between a metal cation and the shared electrons that surround it.

• ionic bond

• covalent bond

• metallic bond

• isotope bond

The metallic bonds in some metals are stronger than those in other metals.

• true

• false

An explanation for some of the properties of metals like ability to conduct electric current and malleability would be

• the mobility of electrons in metals

• the melting point of metals

• the number of protons that metals have

• the covalent bonds between metals

A mixture of two or more elements, at least one of which is a metal.

• metalloid

• alkali metal

• alkaline earth metal

• alloy

Scientists can design alloys with specific properties by varying the types and amounts of elements in an alloy.

• true

• false

Steel is an alloy of iron that contains varying amounts of

• carbon

NGSS.MS-PS1-3

Metallic bonds form between

• metals and nonmetals

• two nonmetals

• two metals

• only transition metals

The lattice in a metal is more rigid than the lattice in a nonmetal, which is why metals are more brittle than nonmetals.

• true

• false
