What is atomic mass of all elements?
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
What is the largest element periodic table?

What is the heaviest element made?
In 2002, a team of Russian and American scientists created the first ever atom of oganesson, which is the heaviest chemical element ever recorded to date. With an atomic number of 118, oganesson filled the final gap in the seventh period of the periodic table as a noble gas.
What element has the smallest atomic mass?
HydrogenThe element which has the smallest atomic mass is Hydrogen (H), which has a proton and an electron.
Is element 119 possible?
Ununennium and unbinilium (elements 119 and 120) are the elements with the lowest atomic numbers that have not yet been synthesized.
Where are the largest elements on the periodic table?
The atomic size decreases towards the right and it increases down the group. Thus the element in left bottom has the largest atomic size.
What is the largest group of elements in the periodic table?
Group 3 is the largest group in modern periodic table as it contains 32 elements. Sc,Y,La,Ac and 14 Lanthanides and Actinides.
Is element 119 possible?
Ununennium and unbinilium (elements 119 and 120) are the elements with the lowest atomic numbers that have not yet been synthesized.
Which element has the largest volume?
What is the largest atom (in terms of volume not atomic mass or weight)? Cesium (Cs), tucked in the lower left hand corner of the table, has the largest known atoms. The atomic radius of Cs is given variously as 273.1 pm [1], 265 pm [2], 265.5 pm [3] or 260 pm [4].
What can cause the atomic weight to deviate significantly from the given value?
Note 3: The isotopic composition of the element can vary in commercial materials , which can cause the atomic weight to deviate significantly from the given value.
How much does lithium weigh?
Note 5: The atomic weight of commercial Lithium can vary between 6.939 and 6.996— analysis of the specific material is necessary to find a more accurate value.
How are chemical elements sorted?
This is a list of chemical elements, sorted by atomic mass (or most stable isotope) and color coded according to type of element. Each element's atomic number, name, element symbol, and group and period numbers on the periodic table are given. The number in parenthesis gives the uncertainty in the "concise notation" dis given in parenthesis next to the least significant digits to which it applies", e.g., 1.00794 (7) stands for 1.00794 ± 0.00007. For artificial elements the nucleon count of the most stable isotope is listed brackets
