What is the number of protons neutrons in radium?
Radium has 88 protons and 138 neutrons.
How many protons electrons and neutrons in lanthanum-138?
Lanthanum has 57 protons and 81-82 neutrons.
How many neutrons are there in isotope Rn 220?
The atomic number is 86 which gives the number of protons. 220Rn has 220 protons and neutrons so the neutron count iscalcualted as follows: 220 -86 = 134 neutrons 220Rn is an unstable isotope of Radon.
How many neutrons in actinium?
The number of neutrons is the difference between the atomic mass of an isotope and the atomic number. Actinium has a great number of isotopes, each with a different mass or number of neutrons.
What element has a mass number of 138 and atomic number of 56?
The element with a mass number of 138 and atomic number of 56 is Barium (Ba). The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number indicates the number of protons. In this case, Barium has 56 protons and 82 neutrons (138 - 56 = 82).

What is the nuclear of a Ba-138?
I am not precisely sure of what this question means. Nevertheless, we can talk of Ba-138 as an isotope, and hope this covers the subject. Ba-138 is a stable isotope of barium. It has 56 protons and 82 neutrons. There is another isotope of barium which also has 56 protons and 82 neutrons called Ba-138m. It has a half life of less than a millionth of a second, and decays into Ba-138.
