How many elements under atomic number 101 have names ending with ium?
Wiki User
∙ 12y ago
39 from main table
+ all 14 lanthanides
+all 14 actinides (but looking for elements<101 so, only 11)
Hence, 64/100 elements with names ending in -ium.

What elements have German names?
All of the elements have German names when writing or speaking in German. However, only one element has an international atomic symbol derived from its German name: That is tungsten, for which the German name is Wolfram and the atomic symbol is W.
What is the difference in the modern periodic table and Mendeleev's table?
The periodic table is now complete and can be displayed using the integral atomic numbers. In Mendeleev's time there were still unknown elements. In fact, one of the primary uses of his table was to predict the properties of elements that had not yet been isolated. (His 1869 table included speculative names for some expected elements.) -- In Mendeleev's periodic table, transition elements were placed in another group. --In Mendeleev's periodic table, noble gases were written on left side. In the modern periodic table, noble gases are written on right side.
How many element are there?
In total there are 118 elements known or predicted to exist, and they appear on the modern Periodic Table.Only 114 of the elements are named, having been fully authenticated by isolation, or by detection of decay products. The others are given provisional (numerical) names with their atomic number, but no atomic weight. Around 98 elements occur naturally in one or more isotopes, and about 28 have to be synthetically produced (man-made).
How are elements represented on the Periodic Table of Elements?
Every element on the periodic table is made of a number of protons and neutrons in the center with electrons around them. What makes one element different from another is the number of protons it has. The number of protons an element has is equal to that element's number on the periodic table.So, for example, Helium, which is element #2, has two protons. Oxygen, element #8, has 8 protons.The element's number that is also its number of protons is the small whole number located above the element symbol. E.g. 8 is written above O for oxygen. (The larger decimal number below the element symbol is something different, the average mass of the element.)
What is the process by which some substances spontaniously emit radiation?
All elements with an atomic number >83 are naturally radioactive
What is the names and chemical symbol for the elements that correspond to the atomic number 10?
10 Neon (Ne)
Give the names of naturally occurring elements?
In the attached list manmade elements are: technetium, promethium and the elements with atomic number between 94 and 118.
What are the elements that do not exist without the use of artificial nuclear reaction on the earth?
All the elements with an atomic number greater than 94. See the periodic table (link) for the names of these elements.
What can we find on the periodic table?
The Periodic table is a table with more than a hundred Elements on it. As of 2010, there are 118. Along with the names of the Elements there is the chemical symbol of the Element, the atomic number, and usually the atomic mass of the Element. The atomic number represents the number of Protons in one atom, and the atomic mass is the mass of the Protons and neutrons added together. The Electrons are not added onto the mass of the Protons and Neutrons because the Electrons are negligible.
What basic information is contained in the Periodic table of elements?
The periodic table include only chemical elements each has a unique atomic number that represents the number of protons in its nucleus. Most elements have differing numbers of neutrons among different atoms these are referred to as isotopes.
What are the names symbols and atomic number of the top four elements in group 1267?
Have a look at the periodic table page on wikipedia. I cannot make out the numbers of the groups.
What to elements does water contain?
An element is a type of atom, determined by the number of protons that it has (also known as its atomic number). As of 2008, 117 elements have been observed. 94 of these are naturally-occurring on Earth. The term element does not imply a particular number of atoms, though often it is used to describe a single atom.
What elements have German names?
All of the elements have German names when writing or speaking in German. However, only one element has an international atomic symbol derived from its German name: That is tungsten, for which the German name is Wolfram and the atomic symbol is W.

On the periodic table what is the name for 254?
There is no element 254. Elements are identified by their names and by their atomic numbers, the number of protons in the nucleus. Atomic numbers do not go up much past 110, if that far. However, element 99, Einsteinium, does have an atomic mass of 254, which describes the total number of protons and neutrons in its most common isotope. Perhaps that is what you mean.
What is the mass number minus the atomic number called?
Nucleon Number (total number of protons and neutrons)
What are the names and numbers of the particles in an atom of sodium?
The atomic number is 11 and atomic mass is 23. The number of protons and electrons in sodium is 11 and the number of neutrons is 12
