Is Hg a homogeneous mixture or hetergeneous mixture?
Pure Hg is homogeneous. It's an element of the periodic table such as iron or oxygen ; it has 80 protons and about 120 neutrons (6 stable isotopes.
How do you find elements on the periodic table with the same substance?
I am sorry, I do not know what you mean by this question. No element on the periodic table is the same. Here are some facts, however.The Periodic Table is a chart which arranges the chemical elements in a useful, logical manner. Elements are listed in order of increasing atomic number, lined up so that elements which exhibit similar properties are arranged in the same row or column as each other. The Periodic Table is one of the most useful tools of chemistry and the other sciences. Here are 10 fun and interesting Periodic Table facts:While Dmitri Mendeleev is most often cited as the inventor of the modern periodic table, his table was just the first to gain scientific credibility, and not the first table that organized the elements according to periodic properties.There are 90 elements on the periodic table that occur in nature. All of the other elements are strictly man-made.Technetium was the first element to be made artificially.The International Union of Pure Applied Chemistry, IUPAC, revises the periodic table as new data becomes available. At the time of this writing, the most recent version of the periodic table was approved 19 February 2010.The rows of the periodic table are called periods. An element's period number is the highest unexcited energy level for an electron of that element.Columns of elements help to distinguish groups in the periodic table. Elements within a group share several common properties and often have the same outer electron arrangement.Most of the elements on the periodic table are metals. The alkali metals, alkaline earths, basic metals, transition metals, lanthanides and actinides all are groups of metals.The present periodic table has room for 118 elements. Elements aren't discovered or created in order of atomic number. Scientists are working on creating and verifying element 120, which will change the appearance of the table.Although you might expect atoms of an element to get larger as their atomic number increases, this does not always occur because the size of an atom is determined by the diameter of its electron shell. In fact, element atoms usually decrease in size as you move from left to right across a row or period.The main difference between the modern periodic table and Mendeleev's periodic table is that Mendeleev's table arranged the elements in order of increasing atomic weight while the modern table orders the elements by increasing atomic number.
What is the atomic notation for Tin-120?
The element with the atomic number 120 is theoretical and hasn't been observed. However, it does still have a systematic IUPAC placeholder name - Unbinilium (Ubn). No attempts have ever been made to create this element. If it were to be discovered, it would fit in under Radium as an Alkaline Earth Metal.
What element has an atomic mass of 120?
The element with the atomic number 120 is theoretical and hasn't been observed. However, it does still have a systematic IUPAC placeholder name - Unbinilium (Ubn). No attempts have ever been made to create this element. If it were to be discovered, it would fit in under Radium as an Alkaline Earth Metal.
Why is the accurate molecular mass of many element not a whole number?
The atomic mass shown on the periodic chart is the weighted average of the naturally occurring isotopes of that element. It works like this: What is the average weight of 4 people where three weigh 120 and one weighs 90? (In this group, the most common weight is 120 so the average will be close to 120) The weighted average is: 75% x 120 + 25% x 90 = 90 + 22.5 = 112.5 All of the member's weights were whole numbers but the average is a fraction. Each isotope, similarly, has a whole number weight but they occur at different percentages. If you see a whole number weight on the periodic chart it is the weight of the longest-lived isotope since it has no naturally occurring stable isotopes...you will sometimes see this weight in parentheses.
What group would an element with 120 protons and 2 electrons go in?
An element with 120 protons would be unbinilium which hasn't been discovered yet. With 2 electrons would make it Ubn118+ which is an ion- not an atom so it is not on the periodic table.
What is element 120 on the periodic table?
There is no element 120. The highest atomic number according to the current periodic table is 118, of which only 3 atoms have been synthesized. There are only 92 naturally occurring elements. The rest have been, or will be synthesized in special laboratories.
How high would the atomic number of a new element need to be to appear under radium in the periodic table?
Element 118 finishes out period 7 at group 18. Radium is in group 2. So, following the trend, the next element under radium would be element 120.

How many periodic tables are there?
There are no compounds in the periodic table, only elements. There are between 114 and 117 elements (some are awaiting confirmation and a couple remain unnamed).
How many valence electrons can an element have?
up to 120 elements 14 can be the maximum no. of valence electrons if any element with atomic no.greater than 120 is discovered its maximum no. of valence electrons would be 18
