How many protons neutrons and electrons are in uranium 236?
U234 occurs naturally in small amounts, 0.0054 percent of total U. 1/2 life is 245,500 years. Number of protons 92 (as for all U isotopes), neutrons 142, electrons 92.
What element is a period 5 transition element with 51 neutrons?
The element you are referring to is Zirconium (Zr), which has an atomic number of 40 and is located in period 5 of the periodic table. Since Zirconium has 40 protons, having 51 neutrons gives it an atomic mass of approximately 91 (40 protons + 51 neutrons). This places it specifically as the isotope Zirconium-91.
Which is the symbol for an atom containing 20 protons and 22 neutrons?
Mo (Molybdenum) Atomic number: 42; Atomic Mass: 91
How many protons does zirconium have?
AnswerThere are 40 protons in the element "zirconium". There are a number of isotopes of Zr, with the most common having an atomic weight (protons plus neutrons) of 90, with 94 and 92 tied for second place. That leaves 50 neutrons as most common, with 52 or 54 neutrons as alternatives.

What element has 92 protons and 146 neutrons?
The element is Uranium , the symbol is (U). The charge is +1 because:Atomic number(Z): # of protons (92), which also tells you what element it is in the periodic table.Ion charge: # of protons (92) - # of electrons (91) = 1Mass number(A): # of protons (92) + # of neutrons (143) =235
What element is a period 5 transition element with 51 neutrons?
The element you are referring to is Zirconium (Zr), which has an atomic number of 40 and is located in period 5 of the periodic table. Since Zirconium has 40 protons, having 51 neutrons gives it an atomic mass of approximately 91 (40 protons + 51 neutrons). This places it specifically as the isotope Zirconium-91.
