Worksheet: Types of Bonding

In this worksheet, we will practice describing the origin and properties of covalent, polar covalent, ionic, and metallic bonding.

Q1:

Which of the following is the least useful piece of information for predicting the type of bonding likely to occur between two elements?

  • ATheir electronegativities
  • BTheir boiling points
  • CTheir melting points
  • DTheir position in the periodic table
  • ETheir electron arrangements

Q2:

In which type of chemical bond are electrons transferred from one atom to another?

  • AIonic bond
  • BHydrogen bond
  • CCovalent bond
  • DMetallic bond
  • EDative bond

Q3:

Which of the following is an accurate definition of a dative covalent bond?

  • AA bond in which two bonding electrons are shared between more than two atoms
  • BA bond comprising more than two shared bonding electrons
  • CA bond comprising two shared bonding electrons that originate from the same atom
  • DA bond in which two bonding electrons are shared unevenly between a pair of bonded atoms
  • EA bond comprising only one shared bonding electron

Q4:

Which of the following molecules and ions does not contain a dative covalent bond?

  • ACS2
  • BCO
  • CHNO3
  • DNH4+
  • EBF4

Q5:

Which force is mainly responsible for the attraction between oppositely charged ions in an ionic compound?

  • AMagnetic force
  • BGravitational force
  • CElectrostatic force
  • DCovalent force
  • EMetallic force

Q6:

In a covalent bond, nuclei (x) interact with an energy 𝐸x-x, electrons (e) interact with an energy 𝐸e-e, and electrons and nuclei interact with an energy 𝐸e-x. The total interaction energy, 𝐸total, is determined by the balance of these interaction energies, as illustrated in the figure.

An interaction energy is positive if it is repulsive and negative if it is attractive.

Which interaction energies are negative?

  • A𝐸e-x, 𝐸e-e
  • B𝐸e-x
  • C𝐸x-x, 𝐸e-e
  • D𝐸e-x, 𝐸x-x, 𝐸e-e
  • E𝐸e-e

Write an expression for 𝐸total in terms of the interaction energies listed.

  • A𝐸=2𝐸+2𝐸4𝐸totale-ex-xe-x
  • B𝐸=𝐸+𝐸+4𝐸totale-ex-xe-x
  • C𝐸=2𝐸2𝐸+2𝐸totale-ex-xe-x
  • D𝐸=𝐸+𝐸+𝐸totale-ex-xe-x
  • E𝐸=𝐸+𝐸𝐸totale-ex-xe-x

If a covalent bond is stable, which of the following conditions must be satisfied?

  • A𝐸<0total
  • B𝐸<𝐸totale-x
  • C𝐸>0total
  • D𝐸>𝐸totalx-x
  • E𝐸=0total
