What element has 2 electrons 3 protons and 4 neutrons?

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

Protons neutrons electrons for lithium?

Lithium has 3 protons, 4 neutrons, and 3 electrons.


Number of protons and electrons in lithium?

Lithium has three protons and three electrons. The number of electrons always equals the number of protons. Lithium has two isotopes, one with three neutrons and one with four neutrons.


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.


What is the mass of an element with 4 protons 6 electrons 3 neutrons?

The mass of the isotope 7Be is 7,01692983(11) u. The isotope 7Be has 4 protons, 3 neutrons and 4 electrons (not 6).


Why are there 3 subatomic particles?

Protons, neutrons, and electrons are the three main subatomic particles in an atom. Protons and neutrons are found in the nucleus while electrons orbit around the nucleus. They have different properties and roles in determining the characteristics of an element.

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


What element has 7 neutrons and 3 electrons?

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.
