The atomic number of Helium is 2 because there are 2 protons and 2 electrons.
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.
2 is the atomic number (or the number of protons) of helium.
Helium has the atomic number 2 and is the second most abundant substance in the universe.
Helium with two protons and two neutrons has an atomic number of 2, as the atomic number corresponds to the number of protons in an atom.
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.

This isotope of helium is helium-3; the atomic number of helium is 2.
Helium with two protons and two neutrons has an atomic number of 2, as the atomic number corresponds to the number of protons in an atom.
The only atom that contains one proton is the hydrogen atom, also called protium. It is neutrally charged with a single proton at its nucleus, and a single electron orbiting. It is possible that you are asking about the isotope of hydrogen called tritium. Tritium is a radioactive isotope of hydrogen that contains a single proton and two neutrons.
The atomic number of helium is 2. Its mass is 4.002602 u ± 0.000002 u
helium has 2 electrons as its atomic number is 2
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.
The atomic number of helium is 2. This number indicates the number of protons in the nucleus of a helium atom. The atomic number of an element determines its chemical properties, such as its reactivity and bonding behavior. Helium's atomic number of 2 means it has a stable configuration, making it a noble gas with low reactivity and high stability.
