Hope this helped :)
By 1869, a total of 63 elements had been discovered.
Ca stands for calcium on the periodic table for the first 2 letters of calcium.
112 Elements ( 92 Natural and 20 Man-made ) .

The first 20 elements in the periodic table are: Hydrogen Helium Lithium Beryllium Boron Carbon Nitrogen Oxygen Fluorine Neon Sodium Magnesium Aluminum Silicon Phosphorus Sulfur Chlorine Argon Potassium Calcium
There are currently 118 elements in the periodic table, with 20 man-made and 88 (not 92) naturally-occurring elements. *Since 23rd October 2008.
Yes, it has the atomic # of 20 on the periodic table of elements.
August 20, 1864 was when John Alexander Reina Newlands produced the first periodic table of the elements.
The first 20 elements of the periodic table are made up of a variety of elements including hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, and calcium.
Conductors in the first twenty elements include; Lithium - Li Beryllium - Be Carbon - C Sodium - Na Magnesium - Mg Silicon - Si Potassium - K Calcium - Ca

No, 3-12 elements on the periodic table (group 3 to group 12) are transition metals, not representative elements. Representative elements are found in groups 1 and 2, and 13 to 18 on the periodic table.

Yes, there are more nonmetals than metals on the periodic table. Nonmetals include elements such as hydrogen, oxygen, and nitrogen, while metals include elements like iron, copper, and gold. The majority of elements on the periodic table are nonmetals.
