Insert the Lewis Structure picture. To insert a picture, click the icon that looks like a tree in a box (Insert Images and Files) that is on the Editing toolbar. Browse and find the file that is your saved picture of the element. Hit Upload. Go to where it states [file:title of file.jpg]. Place your cursor where you want to insert the image on the screen and click. Now, double click the icon of the picture and it will upload. Click "Save" on the top of the screen. Make sure that the page looks how you want it up to this point, then click "Edit" and continue adding information to your page.

Covalent Bonding - (include more than one type of covalent bond) Explain how the element fits with covalent bonding. Include a link to your document.
To link a document, use the same method as you did for the picture. Click the icon that looks like a tree in a box (Insert Images and Files) that is on the Editing toolbar. Browse and find the file that is your saved document. Hit Upload. Go to where it states [file:title of file.doc]. Place your cursor where you want to insert the document on the screen and click. Now, double click the icon of the Word Document and it will upload. Click "Save" on the top of the screen. Try clicking your new link and ensure that it is how you would like it to appear. Now, click "Edit" and continue adding information to your page.

Bond - Explain a different type of bond other than covalent.

Bond - Explain another type of bond.

On another element's page (created by another student), click edit the page and type in this section only. Add a blank line under this area and explain in a sentence or two who you are (element and class period - hydrogen3), what type of bond you would form with the element on this page, and why you would form a bond with this element. After you have typed your sentence, highlight your element name (hydrogen3) and click the "Insert Link" button from the toolbar (Globe with a chain at the bottom). Make sure that the link text and the page name are your element name and period number. Do not change them or put a space in between them. Click "OK" and now "Save" the page. Click on your element name to link back to your element's page. If your page does not appear, ask for assistance and go back and redo the link on this section.
