Is a lead atom heavier than a helium atom?
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.
What does the number 2 indicate in helium?
2 is the atomic number (or the number of protons) of helium.
What atom has an atomic number 2?
Helium has the atomic number 2 and is the second most abundant substance in the universe.
Helium with two protons and two neutrons has a atomic number of what?
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.
What is the mass of a single atom of helium?
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.
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.

What that atom has 1 neutron(s) and 2 proton(s). What is its atomic number?
This isotope of helium is helium-3; the atomic number of helium is 2.
Helium with two protons and two neutrons has a atomic number of what?
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.
Element. All helium atoms have 2 protons. What is the atomic number of helium?
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.
What is the mass number of helium atom?
The atomic number of helium is 2. Its mass is 4.002602 u ± 0.000002 u
How many valence electrons are in an atom of helium?
helium has 2 electrons as its atomic number is 2
What is the mass of a single atom of helium?
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.
What is the atomic number of helium and how does it relate to its properties?
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.
