Is HO4 part of the periodic table?
The Periodic table contains only elements, however, HO4 is a compound and hence has no place on the period table.
How was the person who devised the first periodic table able to predict the behavior of elements such as gallium scandium and germanium that had not even been discovered yet?
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.
Elements are place in the same column of the periodic table because they share the same number of valance electrons.?
Yes, elements in the same column of the periodic table (also known as a group) have the same number of valence electrons. This common valence electron configuration gives them similar chemical properties.
How many elements did Mendeleevs original periodic table have?
In 1863 56 known elements were discovered. Mendeleev's first attempt*) resulted in 9 elements in three rows (periods) and three groups (-1, +1, +2 valence groups):Cl - K - CaBr -Rb -SrI - Cs - Ba*) cit. from wikipedia :"I saw in a dream a table where all elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper, only in one place did a correction later seem necessary."- - - - Mendeleev 1869, as quoted by Inostrantzev.
Who placed all elements in right place according to properties?
In 1869, Dmitri Mendeleev created the first full version of the Periodic Table, including all known elements and leaving places for:Ekaboron or scandiumEkaaluminium or galliumEkamanganese or technetiumEkasilicon or germaniumScientists continue filling up the table as new elements are found, a process that goes on today.
Why is iodine placed on the periodic table of elements?
The periodic table is an array of various elements. Iodine is an element. Hence it finds it place on the periodic table.
What is the important work of dmitr mendeleev?
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.
What is an element in its row in the periodic table?
An elements period is its row in the periodic table.
Where is the place where all elements are known to man are listed?
elements chart
Which elements in the periodic table are by the place?
Metals are placed at the left. Non-metals are placed at right in periodic table.
What properties can be predicted by the elements place on the periodic table?
Monkey123 will fly p456urple
Why are elements place in the same column of the periodic table?
They have similar properties, usually.
Did someone make the periodic table?
Yes, Dmitri Mendeleev made the Periodic Table of Elements, and interestingly enough, he did it without knowing all of the natural elements! As scientists discovered new elements, they realized the elements fit right into place on Dmitri's table.
Who arrange the periodic table of elements?
the place where an element sits on a periodic table is not chosen by anyone. the place where it sits is chosen by it's atomic number or the number of protons it has eg lithium 3 protons its third
Is HO4 part of the periodic table?
The Periodic table contains only elements, however, HO4 is a compound and hence has no place on the period table.
How would the periodic table look if the lanthanide actinide series were in their proper place?
Periodic table would be complex then. It will make study of elements difficult.
What term refers to the number of protons in an atom and helps to place elements on the periodic table?
atomic number
