What is an atom with two neutrons protons and electrons?
If you build an atom using two protons, two neutrons and two electrons you would build an atom of Helium. To be more-precise, this would create Helium-4 the common isotope of Helium.
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.
What would you expect the atomic mass of a helium atom to be Explain your answer?
The atomic mass of a helium atom is approximately 4 atomic mass units (amu). This value reflects the combined mass of its two protons and two neutrons, as helium has two protons in its nucleus and typically two neutrons. The mass of electrons is negligible compared to that of protons and neutrons, so it does not significantly affect the atomic mass. Thus, the expected atomic mass aligns closely with the sum of the nucleons in the helium nucleus.
How many of each of the elementary particles are contained in the helium atom?
A helium atom consists of 2 protons, 2 electrons and 2 neutrons.
What does an atom of 2 protons 2 neutrons and 2 electrons make?
If the atom has a balanced electrical charge, then # of protons = # of electrons, so the atom has 2 protons (Helium). The vast majority of Helium atoms have 2 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.
What is the atomic number o an atom that has 2 protons and 3 neutrons?
2 (helium). With 3 neutrons it would be Helium-5 which is the most unstable radioisotope of helium.

How may electrons neutrons protons are found in the helium?
In normal Helium(He) atom there are 2 electrons, 2protons and 2 neutrons.
What is the diameter of the helium atom?
The nucleus of a Helium atom contains two protons and two neutrons, protons and neutrons are measured in Daltons, and a Helium atom is about 4 Daltons
Is 1 helium atom an atom?
Helium is an element- the second one in the periodic table.
What atom has two protons and two neutrons?
It is helium, specifically the helium-4 isotope, that is composed of two protons and two neutrons.
How can you figure out the number of neutrons in an atom?
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
