What else can I help you with?
Are there 2 neutrons in the helium 4 isotope?
Yes. He-4 isotope has 2 protons, 2 electrons and 2 neutrons
How many protons neutrons and electrons are in helium?
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.
This atom is a of helium -4?
The atom is an isotope of helium called helium-4. It contains 2 protons and 2 neutrons in its nucleus, giving it a total atomic mass of 4 atomic mass units.
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.
Why does helium have an atomic number of 2 and atomic mass of 4?
An atom's atomic weight is the total of all protons and neutrons in its nucleus. Helium almost always contains two protons and two neutrons. Therefore, its atomic weight is 2 + 2 = 4.
Are there 2 neutrons in the helium 4 isotope?
Yes. He-4 isotope has 2 protons, 2 electrons and 2 neutrons
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 protons neutrons and electrons are in helium?
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.
How many protons and neutrons electrons in helium?
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.
How many electrons protons neutrons are in helium?
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.
What has 2 electrons 2 neutrons and 2 protons?
An atom with 2 protons is naturally Helium. Therefore, this isotope would be called helium - 5 because it has 5 particles in its nucleus, 2 protons and 3 neutrons.
What is the number of protons neutrons and electrons for Helium?
protrons=2 electrons=2 neutrons=2
This atom is a of helium -4?
The atom is an isotope of helium called helium-4. It contains 2 protons and 2 neutrons in its nucleus, giving it a total atomic mass of 4 atomic mass units.
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.
Why does helium have an atomic number of 2 and atomic mass of 4?
An atom's atomic weight is the total of all protons and neutrons in its nucleus. Helium almost always contains two protons and two neutrons. Therefore, its atomic weight is 2 + 2 = 4.
How many nuetrons does helium have?
Helium has two protons and two neutrons (and two electrons).
What is the superscript 4 for helium?
4He or He4. 4 stands for the mass number of Helium Mass number = number of protons + number of neutrons Since the atomic number or number of protons in helium is 2, the number of neutrons in He-4 is also 2.
