Create the first carbon atom

To create an atom, you need to select an atom tool.

Select the C-tool by clicking on the button with the 'C'

Back glow is added to the 'C' button to indicate that you are using the C-tool. Also, the status field in the left bottom corner shows 'C tool, create single bond' to indicate that you are using the C-tool.

Now create the first carbon atom:

Click somewhere in the drawing area

One carbon atom has been created.

Note that:

• If you move the mouse you will see a white line from that carbon atom to the current mouse pointer position: this shows you are in 'bonding' mode, and that the bond will be made to the atom just created.
• The 'C' button has a different color, indicating you are still using the C-tool.
• The carbon atom is selected (the green glow), which indicates that the carbon atom is the current selection.
• The status field contains information about the current selection: it is a Carbon, number 0, with 4 'connectors', part of the fragment called 'Untitled'
• The status field also shows the current tool (C), and that a single bond will be made.
