Ionic, Metallic, Covalent Bond Review (2021)

What is the basis of a metallic bond?

• the attraction of neutral metal atoms.
• the attraction between protons and neutrons.
• the attraction between positive metal ions and interlocking electrons.
• the attraction between positive metal ions and free floating electrons.

What does malleable mean?

• able to be shaped
• will break easily
• can be used for wire
• is shiny

Electrons that are free to move in metals are called...

• delocalized electrons.

• trapped electrons.

• unstable electrons.

• positive electrons.

Why do metals conduct?

• They are shiny.

• The electrons are held tightly within the lattice.

• The electrons are able to move throughout the lattice.

• The electrons are shared between two metal ions.

What is the term for a mixture of two or more metals?

• mixture

• solution

• compound

• alloy

Which is written in order if INCREASING bond strength?

• Cl − Cl, H − H, Br − Br

• C ≡ C, C = C, C − C

• P − I, P − Br, P − Cl

Which of these has NO effect on the strength of a bond?

• size of the atoms involved

• number of electrons involved

• temperature of the atoms involved

• all of these directly influence bond strength

Which of these is the most nonpolar?

• Na − Cl

• Cl − Cl

• S − Cl

• Br − Cl

Under what conditions do nonmetal atoms share electrons equally?

• both atoms have the same ionization energy

• both atoms have the same electron affinity

• both atoms have the same electronegativity

• more than one of these results in equal sharing of electrons

The chemical properties of an element are largely determined by the number of valence electrons the element has.

• Always true
• Sometimes true
• Never True
