What element is in period 5 and is a transition element and has 51 neutrons?
The isotope of zirconim, 91Zr, has 51 neutrons. In order to solve this problem, one must know that an element's atomic weight is the average of its number of protons and neutrons (only neutrons are variable). Since the atomic number is the number of protons, the atomic number subtracted from the atomic weight gives the number of neutrons. An element in period 5 that has this many neutrons is found to be zirconium (the isotope 91Zr).
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
I have 20 neutrons and I am found in your teeth and bones?
Calcium is the answer. Atomic weight 40 - with 20 protons means 20 neutrons. Calcium is a key element in teeth and bones.
What element is found in group 14 period 2?
what element is found between period 2 and group 14
How do you determine the number of neutrons in an element?
To determine the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are neutral particles found in the nucleus of an atom.
How many neutrons are on an atom?
The number of neutrons varies with element and isotope. Hydrogen found in nature has 0, 1, or 2 neutrons. Uranium can have from 141 to 146.

Which element in its most common form has no neutrons?
99.985% of hydrogen atoms found in nature have no neutrons.
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
How many neutrons are found in an atom of v?
If you mean the element Vanadium, there are 28 neutrons.
What element has 138 neutron?
The element with 138 neutrons is barium (Ba), which has an atomic number of 56. This means it has 56 protons, and when you add 138 neutrons, you get an isotope of barium with a mass number of 194 (56 protons + 138 neutrons = 194). This isotope is not commonly found in nature but represents one of the heavier isotopes of barium.
What element that is not found in nature that has 161 neutrons?
An element with 161 neutrons would have an atomic number of 2, as the total number of nucleons (protons + neutrons) defines the atomic mass. This would make it a highly unstable isotope of helium, specifically helium-163. However, such an isotope does not exist in nature and would only be produced in a laboratory under specific conditions. It would decay rapidly due to its instability.
What materials are found in lithium?
Lithium is an element, thus it isn't made of anything, apart from 3 protons, 3 neutrons and 3 electrons. It is the third lightest element, and is in the first period of the alkali metals
I have 20 neutrons and I am found in your teeth and bones?
Calcium is the answer. Atomic weight 40 - with 20 protons means 20 neutrons. Calcium is a key element in teeth and bones.
Is there any element which has 86 protons and 136 neutrons?
The chemical element, Radon, has an atomic number of 86, meaning it has 86 protons. Were there an isotope of Radon that had 136 neutrons, it would be labeled as 222Rn. Well, it turns out that this isotope does exist and has a half-life of 3.82 days.
What are found in each element on the periodic table?
Electrons, protons, neutrons
How many neutrons does the element U have?
The amount of neutrons can always be found by taking the atomic number from the mass number. Uranium has 146 neutrons. It depends on the isotope. See the link below for a list of uranium isotopes and how many neutrons are in each. You cannot tell how many neutrons it has with the given information. The most abundant isotope happens to be 238U, which has 146 neutrons.
