How many neutrons helium has?
Helium-4 has 2 protons and 2 neutrons. The less common helium-3 has 2 protons but only 1 neutron. There are also several additional isotopes (that is, different number of neutrons), but those are unstable (radioactive).
What are other differences between lithium and helium?
Helium has an atomic mass of 4.- Number of Protons/Electrons: 2- Number of Neutrons: 2Lithium has an atomic mass of 7.- Number of Protons/Electrons: 3- Number of Neutrons: 4Helium has TWO less neutrons than Lithium.
Are hydrogen-3 and helium-3 isotopes of the same element?
No. hydrogen-3 (tritium) has a nucleus with one proton and two neutrons, and is unstable. Helium-3 has a nucleus with two protons and one neutron, and is stable.
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
What element has 2 protons 1 neutron and 2 electrons?
Helium has 2 protons, 2 neutrons and 2 electrons. The symbol for helium is He and the atomic number is 2.
How many neutrons helium has?
Helium-4 has 2 protons and 2 neutrons. The less common helium-3 has 2 protons but only 1 neutron. There are also several additional isotopes (that is, different number of neutrons), but those are unstable (radioactive).
What is the atomic number o an atom that has 2 protons and 3 neutrons?
2 (helium). With 3 neutrons it would be Helium-5 which is the most unstable radioisotope of helium.
How many neutrons electrons does helium have?
Helium-3 has 1 neutron and 2 electrons. Helium-4 has 2 neutrons and 2 electrons.
List the number of protons electrons and neutrons has helium?
Helium has 2 protons and 2 electrons. He-3 and He-4 isotopes have 1 and 2 neutrons.
How many quarks are in helium?
That depends on the isotope! Choose an isotope, count the total number of protons + neutrons, and multiply the result by 3, since both protons and neutrons have 3 quarks each. Note: in the case of helium, the number of protons is 2 in each case, but the number of neutrons can vary, depending on the isotope. The most common isotope has 2 neutrons, but there are other isotopes as well.
How many neutrons for a given isotope is in helium-3?
Each nucleus of helium-3 contains one neutron.
How many protons and neutrons are in the nucleus of the isootope helium-5?
2 protons 3 neutrons
How many protons are in helium -3?
There are two protons in 3He. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons. So the information about which isotope is (by saying helium-3) is unneeded.
How many neutrons are in helium?
A helium atom typically has two neutrons. This gives helium a total of four particles in its nucleus (two protons and two neutrons), which contributes to its atomic mass of approximately 4 atomic mass units.
How many protons and neutrons and electrons does helium-have?
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons
What is the protons neutrons and electrons of helium?
The number of protons in an element is always the same as the atomic number, which is 2 in the case of helium. (The atomic number is assigned based on the number of protons in an element.) In a neutral atom (one with no charge), the number of electrons equals the number of protons, so it will be 2 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two stable isotopes of Helium, 3He and 4He, having 1 neutron and 2 neutrons respectively. Most helium is helium-4, and helium-3 is found as only about one atom in a million.See link below for more information on Helium, as well as the related question below that will show you how to find the number of protons, neutrons, and electrons in any atom.
What is the number of protons and neutrons in He 3 and He 4?
He-3 and He-4 are isotopes of helium with 1 and 2 neutrons respectively. Both the isotopes have 2 protons and 2 electrons.
