Which of the Following statements about helium atom in the sun and helium atom on earth false?
Both helium atoms in the sun and on Earth have the same properties, as they are identical in terms of their atomic structure and behavior. The only difference is in the environment in which they exist.
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.
Does helium atom in the Sun have the same physical properties as helium atom on Earth?
No. the size of helium is the same everywhere.
How does the mass of a water molecule compare with the mass of helium atom?
The difference is quite large. The helium nucleus (using He4 for fun) contains two protons and two neutrons. The two electrons are way out there happily tucked into there orbitals. A proton is roughly 1825 times more massive than an electron. A neutron is slightly more massive than a proton (by an amount approximately equal to the mass of an electron, as it turns out -- and don't you want to know why?). 4 x 1825 = 7300 The nucleus of a helium four atom is about 7300 times more massive than the electrons in that 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.
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 massive is a alpha particle?
an alpha particle is made of two protons and 2 neutrons. its basically the same as the nucleus of a helium atom
How many times lighter is a helium atom than carbon?
A helium atom is four times lighter than a carbon atom. This is because helium has two protons and two neutrons in its nucleus, while carbon has six protons and six neutrons. The atomic mass of helium is approximately 4 atomic mass units, while the atomic mass of carbon is approximately 12 atomic mass units.
What is the smallest atom?
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
Is 1 helium atom an atom?
Helium is an element- the second one in the periodic table.
