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 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 protons and neutrons are in the nucleus of the isootope helium-5?
2 protons 3 neutrons
How many neutrons for a given isotope is in helium-3?
Each nucleus of helium-3 contains one neutron.
Neutral atom with 53 protons in its nucleus would have how many electrons orbiting the nucleus?
For a standard atom, the number of protons, electrons, and neutrons is the same. For example: 2 Protons - 2 Neutrons - 2 Electrons Helium 3 Protons - 3 Neutrons - 3 Electrons Lithium 4 Protons - 4 Neutrons - 4 Electrons Beryllium So... 53 Protons - 53 Neutrons - 53 Electrons Iodine
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
How many protons and how many neutrons in the nucleus of a helium 4 atom?
2 protons and 2 neutron
How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?
A hydrogen atom has 1 proton in its nucleus. Since the helium-4 atom has twice as many protons as hydrogen, it has 2 protons. Helium-4 also has 2 neutrons, hence the name "4" representing the total number of protons and neutrons.
How many neutrons are in the nucleus of a neutral phosphorus atom?
Atomic mass of phosphorus is 31. It has 15 protons. So it has 16 neutrons.
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).
How many neutrons dose the average helium atom contain?
An average helium atom typically contains two neutrons. Helium has an atomic number of 2, meaning it has two protons in its nucleus. The most common isotope of helium, helium-4, has two protons and two neutrons, resulting in its overall atomic mass of four.
