Is the Mass of hydrogen atom is about the same as a proton?
Yes, in general. All hydrogen atoms contain one proton, most with no neutrons and all neutral atoms with one electron - and the electron has a much smaller mass. Some hydrogen atoms contain one (or, rarely, two) neutrons and so are heavier. But on average the atom has a mass much the same as a proton.
How many hydrogen atoms does the sun have?
Three-quarters of the Sun's mass is hydrogen. How many hydrogen atoms are in the Sun?
How many gold atoms does Au contain?
This depends on the mass of the gold sample.
What don't most hydrogen atoms contain?
Most hydrogen atoms don't contain any neutrons. Deuterium atoms are hydrogen atoms with one neutron each, and tritium atoms are hydrogen atoms with two neutrons each, but most hydrogen atoms are protium atoms, with no neutrons at all. All other atoms in the universe except protium contain at least one neutron each.
What is the most of the mass of an atoms?
The nucleus.
All atoms of an element with atomic number 38 and mass number 88 contain?
All atoms of the specified data contain 38 protons, 38 electrons (assuming they are not ions), and 50 neutrons. They are atoms of the element Strontium.
How many grams of zinc contain 6x10 to the powe of 23 atoms?
To calculate the grams of zinc containing 6x10^23 atoms, we need to determine the molar mass of zinc, which is approximately 65.38 g/mol. Then, we can use Avogadro's number to find the number of moles (n) of zinc atoms: n = (6x10^23 atoms) / (6.022x10^23 atoms/mol). Finally, we can calculate the mass of zinc: mass = n x molar mass.
Most of the mass of the atom is where?
More then 99% of an atoms mass is in the nucleus.
What does most of the atoms mass come from?
the nucleus
Where is most of an atoms mass?
Inside the nucleus.
Does most of the mass in atoms due to electrons?
no
What is atoms mass most made up off?
mass of protons + mass of neutrons
