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 else can I help you with?
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.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
What is lighter than helium but heavier than air?
hydrogen
What are two atoms that are heavier than carbon?
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.

How many times heavier is a sulfur atom than a helium atom?
A sulfur atom is about 32 times heavier than a helium atom. This is based on the atomic masses of sulfur (32 amu) and helium (4 amu).
Is lead heavier than iridium?
Lead has a higher atomic number than iridium, which means a lead atom is heavier than an iridium atom. however iridium is denser, therefore if you had a block of iridium and a block of lead,the iridium block would be heavier
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
What gases are heavier than helium?
Helium exists as a monatomic gas, with atomic mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
Is helium lighter or heavier?
Helium is lighter than air
Are heavier atoms heavier than helium atoms?
yes.
Is air heavy than helium?
Yes. air is heavier than helium.
What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Which has more mass an atom of gold or lead?
An atom of lead has more mass than an atom of gold. This is because lead has a higher atomic number than gold, meaning it has more protons and neutrons in its nucleus, resulting in a greater atomic mass.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
