The most frequent isotope of lithium has 4 neutrons.
Lithium has 3 protons and therefore 3 electrons. Subtracting the mass number from atomic number i.e.. 7 - 3 gives you 4 neutrons.
Lithium has 3 electrons, and therefore 3 protons. It also has 4 neutrons.
In Lithium-5, The number five indicates the mass number or weight in amu's. This is a sum of both the proton and neutrons in an atom. Since Lithium always has 3 protons(otherwise it would be a different element), it can be deduce that it has only 2 neutrons. And usually, unless it is an ion, the number of electrons and protons correspond because protons are negative and therefore they attract negative electrons. So it would also have 3 electrons. In short: 3 protons 2 neutrons 3 electrons
Elements are determined by their number of protons. Nitrogen has 7 protons but usually 7 neutrons as well. What you have here is a nitrogen isotope, an element with more or less neutrons than there are protons. Specifically, this is Nitrogen-15.
This will be an atom with 3 protons, so it has atomnumber 3, which is one of the Lithium isotopes, having 7 neutrons (Li-10, 92%). The other naturally occurring isotope (8%)is Li-9.
7Li or lithium-7.The mass number of an isotope is the sum of the protons and neutrons in its atomic nuclei. The atomic number of Li is 3, so lithium-7 would have 3 protons and four neutrons.
Li-6 has 3 neutrons and Li-7 has 4 neutrons.
li has atomic no. 3 so it has protons= 3 electrons- 3
The number of protons will always be 3 in each Li atom, and either 3 or 4 neutrons, depending on the Li atom's isotope. 6Li has 3 protons, while 7Li has 4. All other isotopes of Lithium are unstable.
Three protons and two electrons.

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-9 has exactly 3 protons, 3 electrons, and 6 neutrons. To Find the number of protons just look on your periodic table, the number usually above the element on the table or the number in bold. (3) Finding the number of neutrons is simply the number preceeding the name (9) minus the number of protons (3).

The atomic mass of Lithium is 6.941. Its has 3 protons and the most common has 4 neutrons.
Elements are determined by their number of protons. Nitrogen has 7 protons but usually 7 neutrons as well. What you have here is a nitrogen isotope, an element with more or less neutrons than there are protons. Specifically, this is Nitrogen-15.
BerylliumThe fourth element in the Periodic Table, Beryllium has four neutrons and electrons, but it doesn't necessarily have four protons. Beryllium is also a type of metal.
This will be an atom with 3 protons, so it has atomnumber 3, which is one of the Lithium isotopes, having 7 neutrons (Li-10, 92%). The other naturally occurring isotope (8%)is Li-9.
