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 neutrons for a given isotope is in helium-3?
Each nucleus of helium-3 contains one neutron.
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.
If one neutron is added to a helium nucleus?
An isotope of helium will be formed.
How many number of neutrons in helium 3?
1 neutron It has in its nucleus 1 neutron and 2 protons so its mass number is 3, hence whay it is called helium-3. (Mass number = # of protons + # of neutrons)
How many isotopes does helium have?
Helium 3 and helium 4 are naturally occurring isotopes 5 thru 10 are exotic isotopes.
How many nuetrons are in helium?
1 neutron in He-3 isotope. 2 neutrons in He-4 isotope (most stable)
What is the netron of xenon?
A neutron is a subatomic particle which is the same for all elements. The neutron for Xenon is the same as the neutron in Helium (4He) or in Ununoctium (294Uuo).
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 the charge of a neutron in helium?
Neutrons have no charge, so in a helium atom, the neutron would also have no charge. Helium typically has two protons (+1 charge each) and two neutrons (no charge), resulting in a neutral overall charge.
What that atom has 1 neutron(s) and 2 proton(s). What is its atomic number?
This isotope of helium is helium-3; the atomic number of helium is 2.
How many protons and how many neutrons in the nucleus of a helium 4 atom?
2 protons and 2 neutron
