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 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.
What is the mass of an isotope of this atom that has 2 neutrons?
It is 3 because you have to add the neutrons and the protons.
What is the mass number of a helium atom that has 2 protons and 2 neutrons?
Number of neutrons = Mass number - Number of protons = 4 - 2 = 2 neutrons
How many neutrons in nucleus of atom for tritium?
2
which atom has 2 protons 2 electrons 2 neutrons?
Helium isotope
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.
