What else can I help you with?
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 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.
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.
How many times heavier is a copper atom compared to an oxygen atom?
A copper atom is about 63 times heavier than an oxygen atom. This is because copper has an atomic number of 29 and oxygen has an atomic number of 8, meaning that a copper atom has approximately 63 times more protons and neutrons in its nucleus than an oxygen atom.
How many times greater is the mass of bromine atom compared to a helium atom?
18.96 times greater = 19.96 times as great.
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).
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.

How many times an atom of sulphur is heavier than an atom of carbon?
An atom of sulfur is about 2.5 times heavier than an atom of carbon. This is because sulfur has a greater atomic mass (32) compared to carbon (12).
How many times greater is the mass of bromine atom compared to a helium atom?
18.96 times greater = 19.96 times as great.
How many times heavier than hydrogen atoms of Carbon and Calcium?
A carbon atom is about 12 times heavier than a hydrogen atom, while a calcium atom is about 40 times heavier than a hydrogen atom. Therefore, carbon atoms are 12 times heavier than hydrogen atoms, and calcium atoms are 40 times heavier than hydrogen atoms.
What is heavier one atom carbon or one atom gold?
The Atomic Mass of Carbon is 12.0107 The atomic mass of Gold is 196.96657 So an atom of Gold is about 16 times heavier than an atom of Carbon.
Is helium atom a single atom species?
Elements are not species. Helium is an element. Helium can be a single atom.
How many electrons does an atom of helium have atomic?
Helium atom has 2 electrons.
How many times an atom of sulfur is heavier than an atom of carbon?
Sulphur has a molar mass of 32.065. Carbon has a molar mass of 12.01. 32.065 / 12.01 = 2.67. So an sulphur atom is 2.67 heavier than an carbon atom.
