There is no stable isotope with 5 nucleons, i.e. 2 protons and 3 neutrons (helium 5). Helium 5 has the shortest half-life of any of the helium isotopes, shorter than helium 8, or helium 9, or helium 10! This presented a problem to physicists trying to explain formation of heavier elements in stars.

Choose the element that is largest.?
The element with the largest number of nucleons is oganesson.
How do you find the number of nucleons?
To find the number of neutrons in an atom, first find the atomic weight of the element and round that number to the nearest whole number. Then, find the atomic number of the element. Subtract that number from the atomic weight and the number of neutrons will be found.
Where is the nucleus of an atom?
The number of nucleons in an atom can vary. A nucleon is either of the two components that make up an atomic nucleus. That's either a proton or a neutron. Different atoms have different numbers of nucleons, and even different atoms of a given element can have different numbers of nucleons (because of isotopic variation). Let's look an a couple of examples to make our point.In hydrogen-1, which is the simplest and most common form of hydrogen, there is one proton in the nucleus of the atom. It has 1 nucleon. In hydrogen-2, there are a proton and a neutron in the nucleus, and that's 2 nucleons. In hydrogen-3, there are a proton and two neutrons in that nucleus, and that's 3 nucleons. In helium-3, there are two protons and a neutron in the nucleus, and that's 3 nucleons. You can see what's happening if you think it through.
What gaseous element has 5 element electrons and fewer neutrons than sodium?
The element with 5 fewer electrons than sodium is not a gaseous element!
What is the mass number of an atom that contains?
nucleons
How many nucleons are present in an element?
There are A + Z nucleons in an element
Choose the element that is largest.?
The element with the largest number of nucleons is oganesson.
What element has 12 protons 13 neutrons and 15 nucleons?
nucleons equal for protons and neutron total. so it should be 25 neucleons.
How can you tell how many nucleons are in an element?
total number of protons and neutrons in the nucleus.
What does the mass number on an element mean?
It tells you how many nucleons (protons and neutrons) there are in the nucleus.
How many protons does boron-5 have?
The "11" refers, precisely, to the number of nucleons.
How do you find the number of nucleons?
To find the number of neutrons in an atom, first find the atomic weight of the element and round that number to the nearest whole number. Then, find the atomic number of the element. Subtract that number from the atomic weight and the number of neutrons will be found.
Mass number of elements?
The number of nucleons present in an element is equivalent to its mass number.
Which particles are found in the nucleus of the atom?
They're called nucleons. The two types of nucleons are protons and neutrons. Protons are positively charged nucleons and determine, in an atom, what element that atom is. Neutrons have no charge and just supposedly add mass to an atom.
Why iron is heavy while sodium is light?
The density of an element depends on the number of the nucleons (protons and neutrons) in the atom nucleus.
What is the relationship between the atomic number and the number of nucleons an atom?
The atomic number of a chemical element is identical to the number of protons.
Why is iron heavy while sodium is light?
The density of an element depends on the number of the nucleons (protons and neutrons) in the atom nucleus.
