How many neutrons electrons does helium have?
Helium-3 has 1 neutron and 2 electrons. Helium-4 has 2 neutrons and 2 electrons.
How many proton neutron electrons in a hydrogen isotope with mass of 2?
1 proton and 1 neutron is needed because the 2 in hydrogen 2 refers to the atomic mass and protons and neutron have a mass of about 2 daltons each.
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
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 neutrons and electrons does the inert gas helium have?
2 protons, 2 electrons He-3 isotope has 1 neutron He-4 isotope has 2 neutrons
What element has only 1 neutron?
The isotope helium-3 has only one neutron. It has 1 neutron, 2 protons and 2 electrons. You can get an atom's number of neutrons by subtracting its atomic number from its mass (nucleon) number.
What element has 1 protons 1 neutrons and 2 electrons?
It is hydrogen element. It is tritium isotope of hydrogen.
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.
What is helium gas mean?
Helium is a gaseous element at STP and has 2 protons, 2 electrons. He-3 isotope has 1 neutron whereas He-4 isotope has 2 neutrons.
An example of an atom that has no charge is one that has A 2 protons 2 electrons and 1 neutron B 1 proton 2 electrons and 3 neutrons C 3 protons 1 electron and 3 neutrons?
The atom that has no charge is option A: 2 protons, 2 electrons, and 1 neutron. This is because the number of protons (positively charged) is equal to the number of electrons (negatively charged), making the atom electrically neutral.
How many protons neutrons and electrons are there in 3He?
3He has 2 protons, 1 neutron, and 2 electrons.
How many neutrons electrons does helium have?
Helium-3 has 1 neutron and 2 electrons. Helium-4 has 2 neutrons and 2 electrons.
How many proton neutron electrons in a hydrogen isotope with mass of 2?
1 proton and 1 neutron is needed because the 2 in hydrogen 2 refers to the atomic mass and protons and neutron have a mass of about 2 daltons each.

What element has an mass number of 2 and 1 neutron?
This is the isotope of hydrogen - deuterium.
What element has 1 neutron and mass number of 2?
This is the isotope of hydrogen - deuterium.
