Which element is 45 on the periodic table of chemical elements?
The element with atomic number 45 on the Periodic Table is Rhodium (Rh).
An atom with a mass number of 45 has three more neutrons than protons What is the atomic number of this atom?
The atomic number is 21: The mass number is the sum of protons and neutrons, while the atomic number is the number of protons, designated n. From the statement of the problem, n+n+3 = 45, or 2n = 42, or n=21.
What element has a mass number of 45?
Rhodium (Rh)
What element has a mass number of 103 and electrons of 45?
Rhodium (symbol Rh, at. no. 45, at. wt. 103)
How many neutrons are in selenium-76?
A simply formula is the atomic mass of selenium (rounded to the whole number) - atomic number = neutrons. So Selenium 76 has 45 neutrons.
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.

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.
