What are the first 20 elements in the periodic table?
HydrogenHeliumLithiumBerylliumBoronCarbonNitrogenOxygenFluorineNeonSodiumMagnesiumAluminumSiliconPhosphorousSulphurChlorineArgonPotassiumCalciumHope this helped :)
When Mendeleev developed the first periodic table there were approximately how many elements known?
By 1869, a total of 63 elements had been discovered.
What percentage is nonmetals in the periodic table?
The percentage of the elements that are nonmetals is less than 80%. 80% is for metals. You cannot say 20% because you still have to count those metalloids.
State which two elements from the first 20 elements of the modern periodic table are not arranged in order of increasing atomic mass?
Took me a while to find but you can spot it eventually. It's Argon (Ar) and Potassium (K). Hope this helps :)
What are the elements of radioactivity?
Some of the elements on the Periodic Table are Radioactive. This means that their nuclei decay to form other elements in a decay chain. There are currently 33 known radioactive elements of which 20 are currently produced synthetically.

What are the 1st 20 elements of the periodic table made of?
The first twenty elements are made up f different things
Is calcium an elemnt?
Yes, it has the atomic # of 20 on the periodic table of elements.
What month was the periodic table created in?
August 20, 1864 was when John Alexander Reina Newlands produced the first periodic table of the elements.
How many elements are arranged on the periodic table?
There are currently 118 elements in the periodic table, with 20 man-made and 88 (not 92) naturally-occurring elements. *Since 23rd October 2008.
What are the uses of the first 20 elements of the periodic table?
The answer is too long for Wiki Answers; please read a book of general chemistry.
When Mendeleev developed the first periodic table there were approximately how many elements known?

Which metal in the first 20 elements is most reactive?
The First 20 Elements in the Periodic Table are;1. Hydrogen2. Helium3. Lithium4. Beryllium5. Boron6. Carbon7. Nitrogen8. Oxygen9. Fluorine10. Neon11. Sodium12. Magnesium13. Aluminium14. Silicon15. Phosphorus16. Sulphur17. Chlorine18. Argon19. Potassium20. Calcium
What are the elements that are conductor from the first 20 elements of the periodic table?
Conductors in the first twenty elements include; Lithium - Li Beryllium - Be Carbon - C Sodium - Na Magnesium - Mg Silicon - Si Potassium - K Calcium - Ca
What are most elements in the periodic table are classified?
Most are metals. There are about 5 metaloids and aproximately 20 gas/liquids.
Are 3-12 elements on the periodic table of elements representative elements?
Yes. All elements from 1-20 are representative elements as they belong to a representative group (i.e. they aren't a transition metal).
