Chemical Bonding and Compounds Review

Flashcards covering key vocabulary, learning intentions, and success criteria for ionic, covalent, and metallic bonding, as well as organic chemistry and crude oil separation.

What is an ionic bond?

The strong electrostatic attraction between oppositely-charged ions.

How are electrons involved in ionic bonding between metal and non-metal atoms?

Ionic bonding involves the transfer of electrons from a metal atom to a non-metal atom.

What physical properties of ionic solids are highlighted in the student booklet?

Ionic solids are hard, brittle, and have a high melting point.

What is a covalent bond?

A bond in which two non-metal atoms share one or more pairs of valence electrons.

According to the lesson success criteria, how do some non-metal elements exist?

Some elements exist as diatomic molecules.

How is metallic bonding described in the student booklet?

Metallic bonding is described as metal ions surrounded by a 'sea' of delocalised electrons.

What is the definition of malleable?

Able to be hammered or pressed into shape without breaking.

What is the definition of conductivity?

The ability of a material to allow electricity (or heat) to pass through it.

Which three physical tests are conducted during the investigation of bonding types?

Tests of melting behaviour, solid conductivity, and solubility/dissolved conductivity.

What does the directing verb EVALUATE require?

Make a judgement about the merit, worth or value of something based on evidence, weighing up positives and negatives to reach an overall result.

What scaffold is provided to plan and write an extended EVALUATE response?

A six-level scaffold.

What visual tool is constructed to summarise the key ideas of ionic, covalent, and metallic bonding?

A concept map.

What is an organic compound?

A compound whose molecules are based on carbon, usually bonded with hydrogen (and often other elements).

What is a hydrocarbon?

A compound containing only carbon and hydrogen atoms.

How is crude oil separated into useful fractions?

By fractional distillation in a distillation column.
