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.
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?
The number of protons is unique for any given element. Each element has a specific number of protons in its nucleus, which determines its atomic number and identity.
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?
The process of positron emission results in a decrease of 1 in the atomic number of the nucleus. This is because a proton is converted into a neutron, emitting a positron and a neutrino in the process.
How does Neutron emission from a nucleus affect an element?
It changes only the atomic mass.
Which subatomic particle identifies an atom of a particular element?
It's the count of one of the subatomic particles in the nucleus, the proton, that is significant in this regard. For example, an atom is hydrogen if and only if it has one proton in its nucleus. It is neon if and only if it has ten protons in its nucleus.
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 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 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.
Which element has 25 number of neutron and 47 mass number?
Titanium (Ti)
How do you find the neutron of the elements?
Atomic Mass of element - the number the protons.
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 is the only particle that can change in number for an isotope?
Neutrons are the only particles that can change in number for an isotope, as they do not affect the chemical properties of an element. Adding or removing neutrons can create different isotopes of an element without changing its identity.
What element has an mass number of 2 and 1 neutron?
This is the isotope of hydrogen - deuterium.
What element has 1 neutron and mass number of 2?
This is the isotope of hydrogen - deuterium.
What is a isopote?
Is two or more atoms of the same element that have different number of neutron.
