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.
Is helium only one type of atom?
There are two naturally occurring isotopes of helium: He-3 (which is very rare, comprising 0.00014% of naturally occurring helium), and He-4 (which comprises the other 99.99986%of naturally occurring helium). Whether helium is one type of atom or not then depends on the definition of "one type of atom"; if He-3 and He-4 are considered different types of atom due to their differing numbers of neutrons, then no, helium is not one type of atom; if He-3 and He-4 are both considered the same type of atom due to their common number of protons, then yes, helium is one type of atom.
How many times lighter is a helium atom than carbon?
A helium-4 atom is just about 1/3 the mass of a carbon-12 atom.
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
What happens to an atom when it emits an alpha particle?
An alpha particle is a helium-4 nucleus. When it captures a pair of electrons, it becomes a helium-4 atom. Alpha particles released in nuclear decay events quickly pick up a pair of electrons from the environment and become those helium atoms, and the atom is said to be electrically neutral.
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.
Does the mass of one helium-4 atom equal one atomic mass unit?
The mass of a helium-4 atom is 4,002 602 amu.

Is helium atom a single atom species?
Elements are not species. Helium is an element. Helium can be a single atom.
Nucleus of a helium atom?
there are 2 protons in a helium atom there are 2 protons in a helium atom
Does one helium 4 atom equal one amu?
No. It equals 4 amu.
Which gas is produced by nuclear fusion?
If you refer to the fusion in stars, 4 atoms of hydrogen-1 combine to form one atom of helium-4.
What has a greater number of atoms a gram of lead or a gram of uranium?
The lead atom is way heavier than the helium atom. We know this by referring to the Periodic Table of Elements. The atomic mass of lead (Pb) is 207, while that of helium (He) is 4. Therefore, we can estimate that an atom of lead is about 50 times heavier than an atom of helium.
If an atom were to have two protons then it would?
It would by definition be Helium (atom number = number of protons = 2) but the nucleus of the stable isotope 4He also contains 2 neutrons (the mass number = total number of p's and n's = 4)
