What else can I help you with?
What element has the symbol Nb?
Niobium, which was once called "columbium".
Which element is Atomic number- 112?
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
Which element has the highest atomic weight?
I believe the heaviest element known so far is called "Ununoctium," found of course in the bottom right hand side of the period table of elements. It is element 118 and its atomic mass is 294. It is a non-metallic noble gas. However, it is only assumed to be gas. To date, only three atoms of this element have ever been reportedly produced, all from the Joint Institute for Nuclear Research in Russia and the Lawrence Livermore National Laboratory in the USA.
Each element has been assigned a number what is it called?
The numbering arrangement of elements is called the atomic number. Atomic number determines the number of protons in an element's nucleus and defines its unique chemical properties.
What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?
The weighted average of the atomic masses of an element's naturally occurring isotopes is called the atomic mass. This value takes into account the abundance of each isotope in nature when calculating the overall average atomic mass of the element.
What element is located in period 6 of the periodic table beneath the formerly called columbium?
Ta -- tantalum. The element formerly called columbium is now Nb -- niobium,
What element has the symbol Nb?
Niobium, which was once called "columbium".
What element has a relative atomic mass of 15.5?
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
When the masses of naturally occurring isotopes of a particular element are averaged the result is called the elements of what?
When the masses of naturally occurring isotopes of an element are averaged, the result is called the element's average atomic mass.

The number of protons in the nucleus of an element is called?
the answer is that it is called a atomic number.
What is the number in front of an element called?
atomic number
What is the number on top of an element called?
The Atomic Number
An element can be identified by its atomic number called?
proton.
What does the number of elements tell you?
The number is called the element's atomic number. The atomic number is the number of protons in the nucleus of the atom of that element.
Each element has been assigned a number what is it called?
The numbering arrangement of elements is called the atomic number. Atomic number determines the number of protons in an element's nucleus and defines its unique chemical properties.
