Smells Section 2 Vocabulary

Front 1

A three-dimensional representation of a molecule that uses sticks to represent bonds and color-coded balls to represent atoms.

Back 1

Ball and Stick Model

Front 2

The shape around an atom with four bonded pairs of electrons.

Back 2

Tetrahedral

Front 3

The space occupied by valence electrons in a molecule, either a bonded pair(s) or a lone pair.

Back 3

Electron Domain

Front 4

The idea that every electron domain in a molecule is as far as possible from every other electron domain in that molecule.

Back 4

Electron Domain Theory

Front 5

The shape around an atom with 3 bonded and one lone pair of electrons.

Back 5

Pyramidal

Front 6

The shape around an atom with two bonded and two lone pairs of electrons

Back 6

Bent

Front 7

A flat triangular shape found in small molecules with three electron domains surrounding the central atom. No lone pairs on the central atom.

Back 7

Trigonal Planar

Front 8

A geometric shape found in small molecules with two electron domains surrounding the central atom. No lone pairs on the central atom.

Back 8

Linear

Front 9

A three-dimensional model that a chemist uses to show how the atoms in a molecule are arranged in space and how they fill this space.

Back 9

Space-filling

Front 10

The __________________________of a molecular compound appears to be directly related to its smell.

Back 10

Shape

Front 11

The currently accepted model explaining how smells are detected in the nose. Molecules fit into receptor sites that correspond to the overall shape of the molecule. This stimulates a response in the body.

Back 11

Receptor Site Theory

Front 12

Bonds that contain 4 electrons.

Back 12

Double Bond

Front 13

Bonds that contain 6 electrons.

Back 13

Triple Bond
