Mendeleev was the only person to develop a periodic table.

Mendeleev organized elements by atomic weight.

The Periodic Table was developed by NASA.

Answer 1

The false statements about Mendeleev and the development of the Periodic Table are:

1. Mendeleev invented all the elements on the Periodic Table. - This statement is false since Mendeleev did not invent any elements; he organized them based on their properties.

2. Mendeleev's table was complete. - This statement is also false, as Mendeleev's table was not complete; it had missing elements that were later discovered and added.

3. Mendeleev was the only person to develop a periodic table. - This statement is false because other scientists, such as Lothar Meyer, also developed their own periodic tables around the same time.

4. The Periodic Table was developed by NASA. - This statement is false; the Periodic Table was developed long before NASA existed, having its origins in the 19th century through the work of scientists like Mendeleev.

So, the false statements from your options are:

• Mendeleev invented all the elements on the Periodic Table.
• Mendeleev's table was complete.
• Mendeleev was the only person to develop a periodic table.
• The Periodic Table was developed by NASA.
