What is the number of protons neutrons in radium?
How many protons electrons and neutrons in lanthanum-138?
Lanthanum has 57 protons and 81-82 neutrons.
What element has a mass number of 138 and atomic number of 56?
The atomic number is the number of protons; 56. The mass number is the number of protons plus the number of neutrons, so 56+82=138. The element is barium, by the way, because of the number of protons.
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.
How many electrons protons and neutrons are in Radium226?
Radium 226 has 88 protons, 88 neutrons, and 138 electrons.
How many protons and neutrons does radium have?
88

How many protons and neutrons that are in actinium?
Actinium has 89 protons and 138 neutrons (the natural isotope 227Ac).
How many protons neutrons and electrons are in radium 222?
Radon has 86 protons, 86 electrons.Rn-222 isotope has 136 (222 - 86 = 136) neutrons
How many protons and electrons and neutrons does actinium have?
Actinium has 89 protons and electrons; the natural isotope 227Ac has 138 neutrons.
What is the number of neutrons in the element radium?
How many proton and neutron are in radium?
What element has a mass number of 138 and atomic number of 56?
The atomic number is the number of protons; 56. The mass number is the number of protons plus the number of neutrons, so 56+82=138. The element is barium, by the way, because of the number of protons.
