Lithium: It has 4 neutrons and 3 protons.
The mass number of an atom is the sum of its protons and neutrons. In this case, the atom has 3 protons and 4 neutrons, so the mass number is 3 + 4 = 7. Electrons do not contribute to the mass number as their mass is negligible compared to protons and neutrons.
He-3 and He-4 are isotopes of helium with 1 and 2 neutrons respectively. Both the isotopes have 2 protons and 2 electrons.
Lithium has 3 protons and typically 4 neutrons in its nucleus.
Lithium has: 4 neutrons 3 electrons and 3 protons --------------------------------------- There are two naturally occuring and stable isotopes of Lithium (Li): 6Li (which constitutes about 4% of natural deposits) and, 7Li (which constitutes about 96% of natural deposits). Both isotopes have 3 protons and 3 electrons. 6Li has 3 neutrons and 7Li has 4. The top answer is probably the one you are looking for.
Lithium has 3 protons, 4 neutrons, and 3 electrons.

The atomic number of Lithium is 3. That means there are 3 protons and 3 electrons.
The mass of the isotope 7Be is 7,01692983(11) u. The isotope 7Be has 4 protons, 3 neutrons and 4 electrons (not 6).
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
There is no such element: an element is neutral, so it has equal numbers of protons and electrons.Impossible:2 protons 4 neutrons and 3 electrons is the IMpossible He-1 isotope with mass number 6 (=2p+4n). Helium does not accept electrons because it is noble.Possible:2 protons 4 neutrons and 2 electrons is (elemental) Helium, isotope with mass number 6 (=2p+4n)3 protons 4 neutrons and 3 electrons is (elemental) Lithium
