Best Answer

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.

What element has 3 protons and 3 electrons?

The only element with three protons is lithium.The isotope lithium-6, has 3 neutrons and is the rarer of the two stable isotopes of lithium.Most lithium is isotope lithium-7, containing 3 protons, 3 electrons, and 4 neutrons. It makes up about 92.5 percent of the lithium found on Earth.

Nitrogen-14 and nitrogen-15 are isotopes of the same element. How do these isotopes?

Nitrogen-14 has 7 protons, 7 electrons, and 7 neutrons. Nitrogen-15 has 7 protons, 7 electrons and 8 neutrons. So, the only way they differ is in the NUMBER OF NEUTRONS.

What element has four protons four electrons and five neutrons?

There are too many electrons. This would be a negative ion of lithium-6 (stable but less common isotope) that does not occur naturally. The element with 3 electrons, 3 protons, and *4 neutrons* is lithium-7, the most common isotope. It forms a stable positive ion (2 electrons).

How many protons neutrons and electrons are in Li?

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
