This atom has three neutrons. The Atomic Mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.
The atomic number of lithium is 3. How many neutrons does an atom of lithium have if it is represented by the symbol shown below?7LiA. 2 neutronsB. 13 neutronsC. 4 neutronsD. 7 neutrons
2 neutrons in He-4 isotope.
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
The atomic weight minus the number of protons = the atom's neutrons.
The lithium ion is essentially the same as the lithium atom, except it has lost 1 electrons. The number of protons and neutrons remain the same. Thus, the lithium ion, Li+ has 3 neutrons, just like the lithium atom.
The atomic mass of Lithium is 6.941. Its has 3 protons and the most common has 4 neutrons.
Lithium has 3 protons. The atomic number and the number of protons will be the same.
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science

Based on the atomic number of lithium there are three protons in a lithium atom.
2 neutrons in He-4 isotope.
The elemnt with atomic number 3 is Lithium. There is no easy way of determining how many neutrons are in an atom, in Lithium there are two stable isotopes, 6Li with 3 neutrons and 7Li with 4. The most common is 7Li. If you ever have to guess because you dont have access to Wikipedia or a table of the elements which shows the different isotopes, there are often the same number of neutrons as protons in stable isotopes.
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
how many protons neutrons and electrons does lithium have? 3 protons 4 neutrons 3 electronsA lithium atom has three protons and so three electrons. The number of neutrons depends on the isotope, with the two naturally occurring stable isotopes of lithium, 6Li and 7Li, having 3 and 4 neutrons respectively.3: In any neutral atom, there are the same number of electrons as of protons, and the number of protons is the same as the atomic number, which for lithium is 3.
A neutral lithium atom has 3 electrons, the same as the number of protons, which is the atomic number of lithium. There is no lithium ion with a charge of 7+. If you mean lithium with a mass number of 7, the number of protons is 3 and the number of neutrons is 4.
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
