its valence electrons, its number of energy levels, how reactive it is, and some properties it has
A periodic table can predict elements that are not yet confirmed or identified.
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
An element's physical and chemical properties. You can also predict what elements will bond with each other.
The reason the periodic table was created in the first place was to illustrate the "periodic" physical properties of the known elements of the time. Because of this, the properties of elements that were "missing" from the table could be extrapolated from the periodic trends seen in the known elements.
The periodic table is an array of various elements. Iodine is an element. Hence it finds it place on the periodic table.
A Periodic table The Periodic Table of the Elements.
An elements period is its row in the periodic table.
atomic number
Mendeleev was the inventor of the Periodic Table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence of elements that had not yet been discovered based on gaps in the table he created. Based on observations of other elements in the groups he was also able to predict the characteristics of these unknown elements as well. NICE! dude
he invented an early version of the periodic table, and was able to use it to predict what unfound elements properties would be he follow the periodic law and place the similar elements according their mass number.
To find the information on certain elements!!Periodic Table lists elements in the increasing order of atomic number.Since elements are grouped in to columns (eg:inert gases), it is easier to predict the chemical behaviour of various elements.
