What is the mass of argon in kilograms?
The atomic mass of argon is 4 g. So one atom of argon will weigh 0.004 kg
Which gas is produced by nuclear fusion?
If you refer to the fusion in stars, 4 atoms of hydrogen-1 combine to form one atom of helium-4.
What is the mass of a single argon atom in grams?
Since Argon has a relative atomic mass of 39.95, and mols = grams / RAM, one could calculate 39.95 / (6.02*10^23) = 6.63 * 10^-23 grams [0.00000000000000000000006634g] for a single argon atom, where 6.022 * 10^23 is roughly Avogadro's constant (the count of atoms in a mole). IF my math is correct.
What is one use of argon?
Argon is used to make argon
For one kind of atom to become another kind of atom which particles of the atom need to be expelled or gained?
It is very unusual for one kind of atom to become another kind atom, however it does happen in radioactive processes. Every element is characterized by a distinct number of protons. For example, all hydrogen atoms have 1 proton, all helium atoms have 2 protons, etc. Atoms also include electrons and neutrons. However, adding or removing electrons or neutrons does not change the kind of atom. For example, a helium atom with 2 electrons or 1 electron is still a helium atom. Alpha decay is an example of a radioactive process in which the number of protons changes (and therefore the kind of atom changes). An alpha particle includes 2 protons and 2 neutrons. When it is expelled from an atom, a new kind atom is formed. This occurs when a uranium atom (92 protons) is changed into a thorium atom (90 protons) + an alpha particle.
What is one atom of noble gas?
For example one atom of helium, one atom of argon etc.; all atoms contain a nucleus (formed from protons and neutrons) and a cloud of electrons.
What do argon and helium form?
They form a mixture of argon and helium. Both argon and helium are noble gasses, meaning that the do not usually react and certainly will not react with one another.
Is Ar a atom or molecule?
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
How many protons are in the nucleus of Ar atoms?
It depends on the identity of the atom. For example, Hydrogen has one proton, but Helium has two.
Is 1 helium atom an atom?
Helium is an element- the second one in the periodic table.
How do you separate helium and argon to get helium?
To get helium you can use fractional distillation of liquid air.-or-If you just wanted to separate helium from a MIXTURE of helium and argon you could use diffusion. Since helium is lighter than air while argon is heaver than air. You can capture the helium as it "diffuses" away from argon.
Does an atom of helium have eight electrons in its outer energy level?
the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
How many kinds of atoms does helium have?
Helium has one kind of atom: helium.
How do you calculate the volume one atom of argon?
If the calculated radius of argon is 71 pm the volume of an atom is 630347 (pm)2.
Is helium only one type of atom?
There are two naturally occurring isotopes of helium: He-3 (which is very rare, comprising 0.00014% of naturally occurring helium), and He-4 (which comprises the other 99.99986%of naturally occurring helium). Whether helium is one type of atom or not then depends on the definition of "one type of atom"; if He-3 and He-4 are considered different types of atom due to their differing numbers of neutrons, then no, helium is not one type of atom; if He-3 and He-4 are both considered the same type of atom due to their common number of protons, then yes, helium is one type of atom.
What two atoms are joined together to form a helium atom?
"Atom" implies there's only one there. If there were more than one atom, you'd have a compound. Since helium's an element, all that's in it is helium.
The actual mass of an atom of argon is is 6.63x10-24g How many atoms are in a 40.0-g sample of argon?
Divide 40g by the mass of one atom to find the number of argon atoms.
