00:01 Hello everyone. Welcome to this tutorial on Features and Color Schemes in GChemTable.
00:07 In this tutorial, we will learn about:
00:11 GChemTable Elemental window and Color schemes.
00:16 For this tutorial, I am using
00:19 Ubuntu Linux OS version 12.04,
00:22 GChemPaint version 0.12.10.and
00:27 GChemTable version 0.12.10.
00:32 To follow this tutorial, you should be familiar with
00:35 Periodic table of elements and * GChemPaint.
00:41 If not, for relevant GChemPaint tutorials, please visit our website.
00:46 Let's now learn about GChemTable application.
00:50 GChemTablecan be installed as a utility software of GChemPaint.
00:55 using Synaptic Package Manager.
00:58 GChemTable is a chemical elements Periodic table application.
01:03 It provides scientific information about elements.
01:08 It shows Periodic table with different Color schemes.
01:13 To open GChemTable, click on Dash Home.
01:17 In the search bar that appears, type "gchemtable".
01:21 Click on Periodic table of the elements icon.
01:26 Periodic table of the elements window opens.
01:30 GChemTable window has Menubar like all window based applications.
01:36 Menubar contains all the commands you need, to work with GChemTable.
01:41 This is a Periodic table of elements, here you can see element buttons.
01:49 To get the name of the element, place the cursor on the element.
01:52 Colors used for buttons in the table are conventional colors of the elements.
01:58 This table is a replica of Modern Periodic table.
02:02 Now let's learn about Elemental window.
02:05 To display it, click on any element button on the periodic table.
02:10 I will click on Carbon(C).
02:13 Elemental window of Carbon opens.
02:16 Elemental Window contains four side tabs-
02:20 Main, Electronic Properties,
02:23 Radii Thermodynamics
02:26 I will explain about each tab one by one.
02:30 By default Main tab is selected.
02:33 It has * Symbol of the element
02:36 Atomic number
02:38 Atomic weight and
02:40 Electronic configuration.
02:43 It has a table with headings Lang and Name.
02:47 Table shows Carbon's name in various languages.
02:53 Next, click on Electronic properties tab.
02:56 This tab shows details about-
03:00 Pauling electro-negativity value
03:02 Ionization energies
03:05 first, second and third Ionization energies in MJ per mol
03:10 Electronic affinities in KJ per mol.
03:15 On the right side, corresponding Show curve buttons are seen.
03:20 Click on Show curve button to view the Chart.
03:24 This is the chart of Electronegativity versus Atomic number(Z). I will close the chart.
03:31 Click on Radii tab.
03:34 This tab shows- Covalent
03:36 Van der Waals and Metallic radii values, all in 'pm'.
03:41 'pm' is pico metre= 10 to the power of minus 12 metres.
03:47 Since Carbon is a non-metal, it does not have Metallic radius value.
03:53 I will close the Carbon window.
03:56 Let's go back to the Periodic table of the elements window.
04:00 Let us click on Sodium(Na) button.
04:04 Click on Radii tab.
04:07 Metallic radii value is shown here.
04:11 Radii tab shows a table of Ionic radii.
04:15 This table contains Ion, C.N, and Value as columns.
04:22 Let us scroll down the table.
04:24 This table gives information about * different Ionic states Sodium exists in.
04:31 Its Coordination number(CN) and * Ionic radii value in 'pm'.
04:37 Elements Chromium, Manganese, Iron, Cobalt, Nickel and Copper have a tendency to form a large number of complexes.
04:48 Let us click on Iron(Fe) button.
04:51 Its elemental window opens.
04:54 Click on the Radii tab.
04:56 Ionic radii table has an extra column named Spin.
05:02 Spin column gives idea about complex formation tendency of Iron.
05:07 Here, High means spin free complexes where electrons are unpaired.
05:13 Low means spin paired complexes where electrons are paired up.
05:20 I will close Iron(Fe) elemental window.
05:23 More details about complex formation are available at this link http://en.wikipedia.org/wiki/Spin_states_d_electrons.
05:28 Click again on the Elemental window of Carbon.
05:33 Click on Thermodynamics tab
05:36 This tab shows Melting Point and Boiling point of Carbon.
05:40 Explore Show curve button on your own.
05:45 I will close the Carbon elemental window.
05:48 Now let's move on to Color schemes.
05:52 Go to View menu and select Color schemes.
05:57 A sub-menu opens with a list of Color schemes.
06:01 Click on No colors.
06:04 All element buttons turn to grey.
06:09 Click on Color Schemes and select Physical states.
06:13 A new Periodic table opens with elements buttons in "Blue" color.
06:18 Except for some in "Black".
06:21 On the top, you can see Temperature(K): scale slider with "zero(0)" as minimum value.
06:28 Below, you can see colors of "Solid-Blue", "Liquid-Green" and "Gas-Red".
06:36 At zero degree Kelvin all the elements are in solid state.
06:41 So they appear in 'blue' color.
06:44 Let us drag the slider to increase the temperature.
06:48 Notice that elements change their Physical state.
06:52 "Blue" color is replaced by Green(liquid) and Red(Gas) colors.
07:00 At 6010 degree Kelvin(six thousand ten) all the elements change to gaseous state.
07:04 All the buttons change to "Red" color.
07:09 Some elements are shown in "black" background.
07:12 Their state is unknown at that Temperature.
07:16 Next let's select Family.
07:19 Selected Family drop down button appears.
07:23 Drop down list has various families with their corresponding colors.
07:27 By default All is selected.
07:31 Each Family of elements appear in a specific Family color.
07:36 Click on the drop down list and select Metalloids.
07:40 Metalloids appear in Green family background color.
07:45 Rest all elements appear in "black" background.
07:49 Go back to Color Scheme, select Electronegativity color scheme.
07:57 Elements with 'red' color have lowest Electronegativity values.
08:01 Elements with 'blue' color have highest Electronegativity values.
08:06 There is gradual change in the color from 'red' to 'blue'.
08:12 Elements with 'pink' color have in between Electronegativity values.
08:18 If no data is available in the database, the element will have a "black" background.
08:23 Let us select Block.
08:27 Elements of each Block appear with allotted block color:
08:31 's' block – blue
08:34 'p' block – reddish brown
08:37 'd' block – green and
08:40 'f' block – Purple.
08:43 Let's summarize what we have learnt.
