What element has a mass number of 197?
Hafnium is the element that has a mass number of 179. Its color is silver, its structure is hexagonal, while the number of neutrons is 106.
The mass number of an element is the number of?
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
Mass number of elements?
The mass number of an element is the total number of protons and neutrons in its nucleus. It is used to identify different isotopes of an element based on the varying number of neutrons. The mass number is usually represented as a superscript to the left of the element's symbol.
If an element has an atomic number of 45 and an atomic mass of 92 the number of protons it has is?
The atomic number always gives the number of protons or electrons. The neutrons are obtained by subtracting the number of protons from the atomic mass. In this example, since 45 is the atomic number, this element has 45 protons. since the mass is 92, the number of neutrons is 92-45= 47. However, this is not really true because the element with 45 as atomic number is rhodium and it has a mass of 103 u and hence a total of 58 neutrons.
What element has a mass number of 103 and electrons of 45?
Rhodium (symbol Rh, at. no. 45, at. wt. 103)
If Bromine has an atomic number of 35 and has 45 neutrons what is its mass number?
The mass number of an element is the sum of its protons and neutrons. Since Bromine has 35 protons (atomic number) and 45 neutrons, its mass number would be 35 + 45 = 80.

What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
How many neutrons does an atom have if it has an atomic mass of 20 and an atomic number of 45?
The nucleus is where all the mass of the atom is to be found and every nucleus is made of Protons and Neutrons which have about the same mass. Together these therefore give the atom its Mass Number. Thus if you know the Mass Number you know how many Protons and Neutrons the atom contains. If you are then told how many Neutrons there are, a simple subtraction of this number from the Mass Number will give you the number of Protons. The number of Protons in an atom defines what is called its "Atomic Number" and this is unique to each element. You can then look up the Atomic Number in a Periodic Table of the Elements and find out which element has that number.
