Atomic mass or cerium?
Cerium is a non metal element. Atomic mass of it is 140.12.
What is the atomic mass for cerium?
132.90546 amu
What element has atomic mass of 58.7?
The element with 58 electrons is Cerium (Ce). It has the atomic number 58. Cerium is a 'Rare Earth' metal in Period 6 (Lanthanide group) of the periodic table. With mass number 140 this Ce is the first and stable isotope (142 is weakly unstable, 141 is a radioactive artificial isotope) [It has 58 electrons in 6 shells with 2 electrons in the outer shell (4f-block), so it is NOT a 'Transition' group metal of the 5d-block starting with 72Hf]
How many protons electrons and neutrons are in Cerium?
Cerium's atomic number is 58. Thus, to be electrically neutral, cerium must have 58 protons and 58 electrons. 140Ce is its most abundant isotope with 140 - 58 = 82 neutrons.
What period on the periodic table does cerium belong to?
Cerium belongs to lanthanoids. Its atomic number is 58.
