How many nutrons are there in helium?
There are two neutrons in a helium atom, along with two protons and two electrons. Helium-4 is the most common and stable isotope of helium, with two protons and two neutrons.
How many nuetrons are in the following elements oxygen bromine helium argon manganese and silicon?
Oxygen=8 Bromine=45 Helium=2 Argon=22 Manganese=30 Silicone=14
How many protons and neutrons are in an a-particle?
2 protons and 2 neutrons (an a-particle is effectively a helium atom without any electrons).
What is the number of protons neutrons and electrons for Helium?
protrons=2 electrons=2 neutrons=2
What atomic particle has two protons and two neutrons?
Any atom with two protons has an atomic number of two and is an isotope of helium. With two neutrons, there are a total of nucleons is four, so the isotope or mass number is four (sum of protons plus neutrons). Therefore the atom is helium-4 or 4He, which is stable (not radioactive) and the most common isotope of helium in nature, account for nearly 100% of all helium.
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 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 electronsprotonsand neutrons does helium have?
Helium has two protons, and, in its neutral state, two electrons. It can have either one or two neutrons.
How many neutrons would you expect to find in a helium atom?
There are several isotopes of Helium and they have different numbers of neutrons. The simplest and most common is Helium-4 which has two neutrons
The nucleus of a helium atom contains four subatomic particles how many neutrons does the helium atom have?
Helium has two neutrons and two protons in its nucleus.
How many nutrons are there in helium?
There are two neutrons in a helium atom, along with two protons and two electrons. Helium-4 is the most common and stable isotope of helium, with two protons and two neutrons.
What element has as many electrons as it has neutrons?
There are particular isotopes that have similar number of electrons and neutrons. Some of these isotopes include hydrogen-2, helium-4, carbon-12 and nitrogen-14.
How many protons and neutrons are in the nucleus of the isootope helium-5?
2 protons 3 neutrons
