Development of the Periodic Table

Mendeleev placed the known _____ into a table.

He left ___ for elements that hadn’t been discovered and made detailed _____ about them.

Mendeleev swapped the order of some elements so that elements with similar properties were in the same _____.

groups, gaps, elements, predictions

The next slide, you will need to type your answers.

You must type your answers with correct spelling and with a comma.

e.g bread, ham, eggs,

bread , ham , eggs - will not register be correct

braed, hm, egs - will not register as correct

Write correct answers in your books
