You can't have 0.946 of a neutron. You've either got a whole neutron or you don't. So the answer is "there is no element with a neutron number of 3.946".
The average number of neutrons in lithium is close to that. Somewhere between about 7.5% and 3.75% of lithium atoms have 3 neutrons; the rest have 4. That nicely brackets an average of 3.946 (which would correspond to 5.4% 6Li)

What subatomic particle determines if an element is an isotope or not?
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
How does Neutron emission from a nucleus affect an element?
Neutron emission from a nucleus can change the atomic mass of an element without affecting its atomic number. This can result in the formation of a different isotope of the element. Neutron emission can also make the nucleus more stable by reducing the neutron-to-proton ratio.
Which of the following is unique for any given element A the number of protons B the number of neutrons C the charge on the electrons D the mass of the neutron?
its atomic numberthe number of neutrons
In alpha and beta decay the parent element and the daughter?
In alpha decay, the parent element releases an alpha particle, which is a helium nucleus consisting of 2 protons and 2 neutrons. The daughter element formed has an atomic number 2 less and a mass number 4 less than the parent element. In beta decay, the parent element undergoes a transformation where a neutron is converted into a proton, emitting an electron (beta particle) and an antineutrino. The daughter element formed has an atomic number 1 more than the parent element.
The process of positron emission results in a change to the atomic nucleus. Is that change a decrease of 1 or a decrease of 2 or an increase of 1 or is there no change?
In positron emission, atomic number decreases by one. That's because a proton in the nucleus of the element that is about to undergo positron emission changes into a neutron. This is beta plus decay, by the way. You'll recall that the atomic number of an element, which is that element's chemical identity, is determined solely by the number of protons in the nucleus. If we "lose" a proton because it changes into a neutron, atomic number will now decrease by one. Check out the links below to related posts.
What is the element with the neutron number 30.69?
There is no element with the neutron number 30.69. Neutron number is always a whole number as it refers to the total number of neutrons in an atom's nucleus. The closest whole number to 30.69 is 31, so an element with a neutron number of 31 could be gallium (atomic number 31).
What particles differ in number in isotopes of the same element?
neutron
What element has the neutron number of 30.69?
This is the weighted average neutron number for the naturally occurring isotopes of nickel, which has the atomic number 28 and the gram-atomic mass of 58.69. In an individual isotope, the neutron number is always the isotopic atomic mass number minus the atomic number, and the same principle applies to the weighted average neutron number for the naturally occurring isotopes of an element.
What element has only 1 neutron?
The isotope helium-3 has only one neutron. It has 1 neutron, 2 protons and 2 electrons. You can get an atom's number of neutrons by subtracting its atomic number from its mass (nucleon) number.
What is the differences between isotope and element?
Regular elements contain regular neutron number and the same number of protons and neutrons. Isotopes have different neutron numbers than the original element, but the same number of protons and electrons.
How do you find the neutron of the elements?
Atomic Mass of element - the number the protons.
What is it called when you have the same element but different mass number?
They are isotopes of that element, they have different neutron numbers.
What subatomic particle determines if an element is an isotope or not?
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
What element has 1 neutron and mass number of 2?
This is the isotope of hydrogen - deuterium.
What element has an mass number of 2 and 1 neutron?
This is the isotope of hydrogen - deuterium.
What is the only particle that can change in number for an isotope?
The Neutron- An element with the same number of protons and electrons, but with a different number of neutrons per atom than the original element is called an "isotope". An isotope will have, for all intensive purposes, about the same chemical and physical properties as the original element. Isotopes are written as the element, followed by a dash, then the number of neutrons in one atom of that isotope (Carbon-13 is an isotope of carbon with 13 neutrons per atom)
Isotopes of the same element differ in the number of what-?
Only the neutron number is different, same proton and electron number.
