What else can I help you with?
Atomic mass or cerium?
Cerium is a non metal element. Atomic mass of it is 140.12.
What is the atomic mass for cerium?
The atomic mass for cerium is approximately 140.12 atomic mass units.
Which element has a mass 100 less than cerium?
Isotopes of curium have masses between 232 and 252. It is your choice to subtract 1oo from (232 to 252) and to found an isotope. I have the same homework!!! The answer is calcium. - Linz The most important isotope of curium has an atomic weight of 247; 247-100 is 147. This is the mass of an important isotope of promethium.
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.
