There are NO compounds in the Periodic Table. They are all Elements.
Some examples are compounds of iodine, samarium, radium, strontium.
Through compounds (one element plus another (only some have been found the periodic table always changes))
The periodic table itself does not contain any acids or alkalis. Acids and alkalis are chemical compounds that can be formed from elements on the periodic table by combining them in specific ways. Some examples of acids include hydrochloric acid (HCl) and sulfuric acid (H2SO4), while sodium hydroxide (NaOH) and potassium hydroxide (KOH) are examples of alkalis.
Ra stands for Radium on the periodic table. Radium is a radioactive element with atomic number 88 and is commonly used in medicine for some cancer treatments.
No, the elements in all groups do not ionise. Some of the elements share electrons to form compounds.
Element number 38 on the periodic table is strontium (Sr). It is a soft, silvery metal that is highly reactive with air and water. Strontium is commonly used in fireworks, flares, and as a component in some medical and dental applications.
No. Fluorine is the most reactive halogen. It forms compounds even with some inert gases.
Some common questions about the periodic table include: What is the periodic table? How is it organized? What do the numbers and letters on the table represent? Why are some elements grouped together? How many elements are there in total?
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
Some are, some are not.
No element in the periodic table begins with the letter J.
No element is excluded from the table.
