Helium atom has 2 protons and 2 neutrons (that accounts for its atomic weight). The atomic weight of helium is 4.00260
Yes, a lead atom is heavier than a helium atom. Lead has an atomic number of 82, while helium has an atomic number of 2. Atomic number represents the number of protons in an atom's nucleus, and since lead has more protons than helium, it is heavier. Additionally, lead has a higher atomic mass (207.2 amu) compared to helium (4.0026 amu), further confirming that lead is indeed heavier than helium.
Helium atom has 2 electrons.
Helium's atomic weight = 4 amu
The atomic number of Helium is 2 because there are 2 protons and 2 electrons.
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the 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.

Helium atom has 2 electrons.
Helium has atomic number 2. That means the helium atom has 2 protons and two electrons. The standard atomic weight of helium is 4.002602, or 4.003 rounded to 3 decimal places.
4.002602 g/mol
Helium's atomic weight = 4 amu
The atomic number of Helium is 2 because there are 2 protons and 2 electrons.
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.
4.0026 amu
The mass of a helium atom is approximately 4 atomic mass units (amu), which is equivalent to 4.002602 atomic mass units.
This isotope of helium is helium-3; the atomic number of helium is 2.
